Biotherapeutic products are manufactured in immortalized cell lines, most commonly HEK293. Residual DNA from HEK293 lines can harbor tumorigenic genetic sequences or retroviral sequences that could be transmitted through the biotherapeutic to the human recipients. Accurate quantification of HEK293 DNA is essential to produce a safe and appropriate therapeutic dose. However, the standard methods used for such quantification, like qPCR, face challenges due to lack of specificity and reproducibility. The Vericheck ddPCR HEK293 Residual DNA Quantification Kit, with a novel 5-plex ddPCR assay, has been designed to quantify residual HEK293 DNA in biotherapeutics with high specificity and reproducibility, without the need for reference curves.
The Vericheck ddPCR HEK293 Residual DNA Detection Kit provides:
