sensitivity of nucleic acid amplification techniques (NAT), specifically qPCR\/real-time PCR, for mycoplasma detection. These standards contain defined nominal amounts of mycoplasma (10 CFU per tube) and are intended to be mixed with sample matrix to produce a test solution (e.g., 10 CFU\/mL) for downstream DNA extraction and qPCR detection. The standards support method validation and performance verification in accordance with pharmacopeial guidance (EP\/USP\/JP), where NAT sensitivity targets include 10 CFU\/mL to replace culture methods and 100 CFU\/mL to replace indicator cell culture methods. The product is not for culture and is intended for research use only. Compatible with MycoSHENTEK® Mycoplasma DNA Extraction Kit and MycoSHENTEK® Mycoplasma DNA Detection Kit for complete workflow validation.\u003c\/p\u003e\r\n    \u003c\/section\u003e\r\n\r\n    \u003csection class=\"shentek-section\"\u003e\r\n        \u003ch3 class=\"shentek-subtitle\"\u003eTechnical Specifications\u003c\/h3\u003e\r\n        \u003cdiv class=\"shentek-table-wrapper\"\u003e\r\n            \u003ctable class=\"shentek-table\"\u003e\r\n                \u003cthead\u003e\r\n                    \u003ctr\u003e\r\n                        \u003cth\u003eParameter\u003c\/th\u003e\r\n                        \u003cth\u003eDetails\u003c\/th\u003e\r\n                    \u003c\/tr\u003e\r\n                \u003c\/thead\u003e\r\n                \u003ctbody\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eNominal concentration\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003e10 CFU per vial (when reconstituted to 1 mL final volume → 10 CFU\/mL)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eAvailable strains \/ catalog\u003c\/td\u003e\r\n                        \u003ctd\u003eMycoplasma orale (Product No. 1501501), Mycoplasma pneumoniae (Product No. 1501503), Mycoplasma hyorhinis (Product No. 1501505)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eKit format \/ quantity\u003c\/td\u003e\r\n                        \u003ctd\u003eEach strain: 10 CFU × 5 tubes; DNA Dilution Buffer (DDB): 1.5 mL × 5 tubes\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eStorage conditions\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003eStrains: -65 °C; DNA Dilution Buffer: -20 °C\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eShelf life\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003e6 months (check expiration date on labels)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003ePreparation guidance\u003c\/td\u003e\r\n                        \u003ctd\u003eThaw at 2–8 °C.

sensitivity of nucleic acid amplification techniques (NAT), such as qPCR, for detection of mycoplasma contamination. The standards provide defined quantities (10 CFU) of specific Mycoplasma strains for use as spike-in or positive controls to assess assay sensitivity and workflow performance. They are intended to support replacement of traditional culture methods with validated NAT approaches in accordance with pharmacopeial guidance (EP, USP, JP). The standards are not intended for culture. The product is supplied with DNA Dilution Buffer (DDB) to prepare test solutions and is compatible with MycoSHENTEK® Mycoplasma DNA Extraction Kit and MycoSHENTEK® Mycoplasma DNA Detection Kit for downstream extraction and real-time PCR analysis.\u003c\/p\u003e\r\n    \u003c\/section\u003e\r\n\r\n    \u003csection class=\"shentek-section\"\u003e\r\n        \u003ch3 class=\"shentek-subtitle\"\u003eTechnical Specifications\u003c\/h3\u003e\r\n        \u003cdiv class=\"shentek-table-wrapper\"\u003e\r\n            \u003ctable class=\"shentek-table\"\u003e\r\n                \u003cthead\u003e\r\n                    \u003ctr\u003e\r\n                        \u003cth\u003eParameter\u003c\/th\u003e\r\n                        \u003cth\u003eDetails\u003c\/th\u003e\r\n                    \u003c\/tr\u003e\r\n                \u003c\/thead\u003e\r\n                \u003ctbody\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eTarget sensitivity\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003e10 CFU\/mL (prepared by adding sample matrix to 1 mL to achieve final concentration of 10 CFU\/mL)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eProvided concentration per tube\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003e10 CFU per tube (each strain: 10 CFU × 5 tubes)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eIncluded strains\u003c\/td\u003e\r\n                        \u003ctd\u003eMycoplasma orale (NNE006), Mycoplasma pneumoniae (NNE009), Mycoplasma hyorhinis (NNE008)\u003c\/td\u003e\r\n                    \u003c\/tr\u003e\r\n                    \u003ctr\u003e\r\n                        \u003ctd\u003eStorage conditions\u003c\/td\u003e\r\n                        \u003ctd class=\"shentek-text-danger\"\u003eStrains: -65 °C;

class=\"shentek-text\"\u003eSHENTEK® Reverse Transcriptase Assay Kit is a research-use kit for detecting reverse transcriptase (RT) activity using MS2 RNA as template, followed by reverse transcription and fluorescent qPCR detection. The assay follows the reverse transcriptase activity test method referenced in the Chinese Pharmacopoeia. The kit is designed for testing animal cell matrices used during production and verification of biological products.

Description\u003c\/h2\u003e\n\u003cp class=\"shentek-text\"\u003eThe SHENTEK® MVM Analysis Kit is a real-time PCR based qualitative assay serving as an analytical quality control reagent engineered exclusively for the molecular evaluation of MVM target sequences (covering strains i, p, m, and c) in industrial cell lines and related bioprocessing matrices (examples: CHO, BHK, NS0). Optimized for compatibility with the SHENTEK® Nucleic Acid Extraction Kit (Product No. 1506730), the assay includes an MVM-specific primer\/probe mix, an internal process control (IPC), and a positive control to monitor nucleic acid recovery and amplification. Combined with SHENTEK extraction, the kit enables the efficient recovery and highly sensitive analysis of target DNA from complex matrices such as cell suspensions and in vitro cell culture supplements. The assay demonstrates high specificity, with no cross-amplification observed against tested cell lines and non-target genomes, achieving a limit of testing (LoD) of 50 copies per reaction. The kit is supplied for 50 reactions.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection class=\"shentek-section\"\u003e\n\u003ch3 class=\"shentek-subtitle\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv class=\"shentek-table-wrapper\"\u003e\n\u003ctable class=\"shentek-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntended use\u003c\/td\u003e\n\u003ctd\u003eQualitative detection of Minute Virus of Mice (MVM) strains i, p, m and c in mouse-derived cell lines and serum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit size\u003c\/td\u003e\n\u003ctd\u003eReagents for 50 reactions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalytical sensitivity (LOD)\u003c\/td\u003e\n\u003ctd class=\"shentek-text-danger\"\u003e50 copies per reaction\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecificity\u003c\/td\u003e\n\u003ctd\u003eNo cross-amplification observed with tested engineered cell lines (CHO, VERO, 293T, MDCK, NS0, Sf9) or engineered bacteria genomes (E. coli, Pichia pastoris)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReaction volume\u003c\/td\u003e\n\u003ctd\u003e30 µL total reaction volume (20 µL qPCR MIX + 10 µL purified sample \/ control \/ NTC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eqPCR mix composition (per reaction)\u003c\/td\u003e\n\u003ctd\u003eqPCR Master MIX 15.9 µL; MVM Primer \u0026amp; Probe MIX 2.4 µL; VIR IPC MIX 1.7 µL; (add 0.5 µL VIR IC to mix if not added during extraction); total qPCR MIX = 20 µL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal cycling conditions\u003c\/td\u003e\n\u003ctd\u003eActivation: 95 °C 10:00; 40 cycles of: Denaturation 95 °C 00:15, Annealing\/Extension 60 °C 01:00 (fluorescence read during annealing\/extension)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControls provided \/ required\u003c\/td\u003e\n\u003ctd\u003eVIR Internal Control (IC) included; Positive Control (MVM Positive Control) is referenced (Product No. 1506747) and recommended; Negative control (DDB or 1×PBS) and NTC required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAcceptance criteria — control wells\u003c\/td\u003e\n\u003ctd\u003eNTC: FAM undetected; VIC: Ct \u0026lt; 35 for duplicate runs.

lines (e.g., CHO) and related sample matrices used in biopharmaceutical production. The kit is designed to be used together with the SHENTEK® Virus DNA \u0026amp; RNA Extraction Kit (Product No. 1506730). The assay includes a Vesivirus 2117 Positive Control and a VIR Internal Control (IC) to monitor extraction and amplification. The method achieves a sensitivity of 50 copies per reaction, demonstrates high specificity without cross‑amplification of a range of cell line and microbial genomes, and is suitable for detecting viral RNA from complex matrices such as cells and serum.

engineered exclusively for the molecular evaluation of Vesivirus 2117 target sequences in mammalian cell lines (e.g., CHO) and related sample matrices utilized in biopharmaceutical production. The kit is optimized for compatibility with the SHENTEK® Nucleic Acid Extraction Kit (Product No. 1506730). The assay includes a Vesivirus 2117 Positive Control and an Internal Process Control (IPC) to monitor nucleic acid recovery and amplification. The method achieves a limit of testing (LoD) of 50 copies per reaction, demonstrates high analytical specificity without cross-amplification against a range of cell line and non-target genomes, and is highly suitable for the analysis of target RNA from complex matrices such as cell suspensions and in vitro cell culture supplements. Strictly for Industrial Bioprocessing Quality Control and In Vitro Analytical Use Only.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection class=\"shentek-section\"\u003e\n\u003ch3 class=\"shentek-subtitle\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv class=\"shentek-table-wrapper\"\u003e\n\u003ctable class=\"shentek-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eForm\u003c\/td\u003e\n\u003ctd\u003eArmored RNA positive control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume\u003c\/td\u003e\n\u003ctd\u003e100 μL × 3 tubes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage temperature and stability\u003c\/td\u003e\n\u003ctd\u003eStored below -65 °C;
