SHENTEK® Residual E1B DNA Quantitation Kit is used to quantitate residual E1B DNA from host cell, such as HEK293 cell and its derivative cell lines (e.g. 293T and 293F, etc.), in different stages of biopharmaceutical products, from in-process samples to final products. This kit utilizes fluorescent quantitative PCR technique to perform rapid, specific, and reliable quantitation assay for residual E1B DNA. IPC (Internal Positive Control) is included in the kit to evaluate the performance of each PCR reaction. The kit provides E1B linear DNA Control for customers to detect of linearized samples. For extraction information, please refer to the SHENTEK® Residual Host Cell DNA Sample Preparation Kit User Guide (Product No. 1104191).
