Lentivirus Vector RNA Copy Number Detection Kit

This kit utilizes fluorescently labeled specific probes or dyes that bind to specific sequences in lentiviral nucleic acids. During PCR amplification, real-time monitoring of DNA amplification is achieved by detecting changes in fluorescence signals, enabling accurate determination of lentiviral nucleic acid copy numbers and thereby quantifying lentiviral titers.


Detection Method: This kit employs the TaqMan fluorescent probe-based qPCR method to detect vector RNA copy numbers for lentiviral titer determination.


Application Scenarios: Suitable for lentiviral testing, process development, process validation, production release, and stability studies.

Result Summary


Result comparison between p24 and lentiviral vector RNA copy number


Comparison of specific efficiency (physical titer/Transducing Titer)  based on p24 and lentiviral vector RNA copy number


Data from Figure above indicate that viral particle counts detected using Vector RNA Copy Number are significantly 

closer to transduction titer results compared to p24-based detection. Lentivirus Vector RNA Copy Number Detection Kit 

provides more accurate measurement of lentiviral physical titers.
