For Research Use Only (RUO)
Product Description
SHENTEK® Residual Vero DNA-154 Quantitation Kit is a research-use qPCR kit for quantitation of residual Vero host cell DNA in biopharmaceutical samples (in-process to final products). The kit uses a fluorescent quantitative PCR (FAM reporter) assay with a pre-formulated primer & probe mix and Vero DNA Control standard to enable rapid, specific and reliable quantitation down to the femtogram (fg) level. The kit supplies Vero DNA Control as a reference standard and DNA Dilution Buffer for standard curve preparation. For nucleic acid extraction recommendations, refer to the SHENTEK® Residual Host Cell DNA Sample Preparation Kit User Guide (Product No. 1104191).
Technical Specifications
| Parameter | Details |
|---|---|
| Intended use | Quantitation of residual Vero host cell DNA in biopharmaceutical samples (in-process and final products) |
| Assay format | Fluorescent quantitative PCR (TaqMan-style probe); absolute quantitation using standard curve |
| Sensitivity | Detectable at femtogram (fg) level (documented serial dilutions down to 0.0003 pg/μL = 0.3 fg/μL) |
| Standard curve concentrations | Prepared from Vero DNA Control: ST0 3000 pg/μL; ST1 300 pg/μL; ST2 30 pg/μL; ST3 3 pg/μL; ST4 0.3 pg/μL; ST5 0.03 pg/μL; ST6 0.003 pg/μL; ST7 0.0003 pg/μL |
| Reaction volume | 30 μL total reaction (20 μL qPCR MIX + 10 μL sample) |
| qPCR MIX composition (per reaction) | qPCR Reaction Buffer 17 μL + Vero Primer & Probe MIX-154 3 μL = 20 μL qPCR MIX |
| Thermal cycling conditions | Activation: 95 °C 10:00 (1 cycle); Denaturation: 95 °C 0:15 (40 cycles); Annealing/Extension: 60 °C 1:00 (read fluorescence during this step) |
| Reporter / Reference dyes | Reporter: FAM; Passive reference: ROX |
| qPCR instrument compatibility | SHENTEK-96S, ABI 7500, Bio-Rad CFX96, Linegene 9600plus (and similar real-time PCR systems) |
| Triplicates recommended | Triplicate measurements recommended for standards, controls and test samples |
| Quality criteria / acceptance | ERC recovery rate should be 50%–150%; Ct of NTC should be ≥35 or undetermined; Ct of NCS should be larger than mean Ct of lowest standard (or below validated LOQ if applicable) |
| Stability | Kit components stable up to 24 months when stored as instructed (-20 °C) |
