The Vero Host Cell Residue DNA Size Analysis Kit is designed for the quantitative analysis of Vero residual DNA fragments of various lengths in intermediates, semi-finished products, and final products of biological preparations. This kit utilizes the qPCR fluorescence probe principle to specifically and rapidly detect Vero DNA residues both below and above 200 base pairs, with a quantification limit as low as 10 fg/μL. It also includes the Vero DNA Control (DNA quantitative reference). This kit can be used in conjunction with the company's magnetic bead-based residual DNA sample preparation kits (Cat#18461ES). Validation Report Feature Compliance with regulations: the products are fully validated according to the requirements of Chp, USP, ICH, etc., and their performance is in line with Chinese and foreign regulations and standards; Guarantee of quality: the raw materials of the kits are all self-developed, and the qPCR Mix and other enzyme products are produced in an ultra-clean enzyme factory; High sensitivity: the limit of quantification can reach 3fg/μL level; High precision: high intra-batch repeatability and low inter-batch variation; Strong exclusivity: specific detection of residual DNA in Vero cells without interference from other exogenous genomic DNA; Strong anti-interference: add internal control (IC), easy to exclude sample interference, reaction preparation abnormalities and other factors.

Figures Limit of quantification The primer probes of the four fragments, 97bp, 154bp, 219bp and 507bp, were used to detect Vero DNA at 30pg/μL, 300fg/μL, and 3fg/μL, respectively, with 10 replicates for each concentration. The results showed that at concentrations of 3 fg/μL and above, the CVs of the four fragments were
