This kit uses the Taqman probe quantitative PCR method to quickly detect residual Chinese Hamster Ovary (CHO) host cell DNA in intermediates, semi-finished products and finished products of various biological products and pharmaceuticals. The kit introduces an uracil-N-glycosylase (UNG) system, which can effectively remove residual contamination of PCR products and great reduce false positives caused by contamination of amplified products. The reagent components contain internal standard control (IC), we can monitor whether the reaction process is proceeding normally and eliminate sample interference; ROX is suitable for ABI fluorescence quantitative PCR instruments or other similar equipment, and plays a role in optical path correction.
This product is suitable for biological drug solutions, finished products, semi-finished products, intermediate products or process monitoring samples produced using Chinese Hamster Ovary cells (CHO-K1，CHO-S，CHO-DG44，CHO-GS and other cell lines) as hosts. To obtain a calibration curve for quantitative sample DNA, the kit contains DNA calibrators with 6 concentration gradients (300 pg/μL to 3 fg/μL) for preparation of the calibration curve.
For residual DNA extraction from CHO host cells, it is recommended to use our company’s universal residual host DNA sample pretreatment kit. Before first use, it is recommended to complete a product suitability study: confirm whether there are interferences or inhibitors in the sample or sample matrix, and select appropriate sample detection dilution conditions.
