Product Description

SHENTEK® CAR/TCR Transgene Copy Number Quantitation Kit is designed to quantify the copy number of target genes in human cell products derived from common HIV-1 lentiviral vectors (e.g., CAR or TCR genes integrated in CAR-T and TCR-T cell genomes). The kit uses a multiplex qPCR assay to detect DNA sequences related to the integration/expression elements on the transfer plasmid and a Single Copy Gene (SCG) in human cells, enabling calculation of average copies of target gene per cell. The kit includes a company-produced reference standard and an internal positive control (IPC). The assay is intended for rapid, specific, reliable and universal lentiviral vector applications. For Research Use Only.

Features

  • Multiplex absolute quantitation: Simultaneous detection of CAR/TCR target, single copy gene (SCG) and IPC in the same reaction for absolute copy number determination using a standard curve.
  • Reference standard included: Proprietary reference standard supplied and pre-dilution scheme provided for a 5-point standard curve.
  • Ready-to-use primer & probe mixes: Pre-formulated CAR/TCR Primer & Probe MIX and IPC MIX simplify assay setup and reduce pipetting error.
  • Compatible with common qPCR platforms: Validated for use on SHENTEK-96S, ABI 7500, LineGene 9600plus, CFX96 and similar real-time PCR instruments.
  • Designed for lentiviral vector applications: Optimized for quantifying transgene copy numbers from HIV-1 derived lentiviral vectors (CAR/TCR).

Applications

  • Quantification of CAR or TCR transgene copy number in CAR-T and TCR-T cell products
  • Lentiviral vector integration assessment
  • Preclinical and research cell therapy product characterization
  • Quality control and batch testing for gene-modified cell products (research use)

Attention

• For Research Use Only (RUO). Not for use in diagnostic procedures.

• Read Material Safety Data Sheets (MSDS) and follow handling instructions; wear protective eyewear, mask, clothing and gloves.

• Work in a clean environment: irradiate bench, pipettes and tubes with UV for 30 minutes and disinfect with 75% ethanol to avoid contamination.

• Avoid assay inhibitors; monitor IPC Ct — if sample IPC Ct is significantly higher than NCS IPC Ct, sample may be inhibitory.

• NTC and NCS Ct should be larger than the mean Ct of the lowest standard concentration.

• Prepare and run triplicates for standards, NTC, NCS and test samples where possible.

• Recommended sample input per well: 5 ng–30 ng total DNA (optimize as needed).

• Store kit components as labeled (-20 °C) and protect from light; kit stable up to 24 months. If DDB is cloudy, heat to 37 °C until clear.

• Seal plates/tubes, mix and briefly centrifuge before running; follow instrument-specific setup and analysis instructions.

Frequently Asked Questions (FAQ)

Q1: What sample type and amount should I use for the assay?
Use purified genomic DNA from CAR-T, TCR-T or other cells with lentiviral integration. The recommended total DNA per well is between 5 ng and 30 ng; adjust based on preliminary experiments.
Q2: How is transgene copies per cell calculated?
Calculate CAR or TCR copies per cell using the formula: CAR or TCR copies/cell = 2 × (CAR or TCR / SCG), where CAR/TCR and SCG quantities are measured from the standard curve (copies/μL).
Q3: What are the qPCR thermal cycling conditions?
Activation 95 °C for 10:00 (1 cycle); Denaturation 95 °C for 00:15 (40 cycles); Annealing/Extension 60 °C for 01:00 with fluorescence read during this step.
Q4: How should I interpret IPC and control results?
Mean Ct-IPC of sample should be within ±1.0 of the NCS Ct-IPC; a significantly higher IPC Ct indicates possible inhibition. NTC and NCS Ct values should be larger than the mean Ct of the lowest standard.
