The Lenti-X Provirus Quantitation Kit allows you to rapidly determine the copy number of integrated lentiviruses (proviruses) present in a mixed or clonal population of transduced cells. The kit includes a genomic DNA purification kit, and all the reagents required to conduct 200 SYBR® Green-based qPCR reactions using either the calibrated control template or purified cellular genomic DNA.
Determine Precise Effective Lentivirus Titers
By quantifying the number of lentiviruses that have integrated into the nuclear DNA of your target cells, you can precisely determine the real titer (i.e., effective titer) of your lentiviral supernatant stock and use this information to infect cells with greater precision and more highly defined MOI (multiplicity of infection), allowing you to predict how many viral genomes will integrate into your cells. You can also use this method to calibrate other titration methods which measure virus content in packaging cell supernatants but do not measure functional integrative titers in your target cells.
Predictable and Consistent Lentiviral Transgene Expression
When using lentiviral vectors to deliver transgenes into target cells, expression levels increase with increasing MOI because more lentivirus copies integrate into the nuclear DNA of the cells. Also, for a given virus prep, its effective MOI across different target cell lines can vary widely depending on each cell line’s individual susceptibility to lentivirus infection. The Lenti-X Provirus Quantitation Kit allows you to assess the results of your transductions in any cell line, independent of expression level, and can be used to ensure consistent transductions across different cell lines or when using different virus preparations.
