SHENTEK® Residual 293T RNA Quantitation Kit is used to quantitate residual 293T cell total RNA in different stages of biopharmaceutical products, from in-process samples to final products. Through the designing of specific primers and probes, the reverse transcription and fluorescence quantitative PCR detection techniques were employed to achieve a one-step quantitative detection of residual total RNA. This kit performs a rapid, specific, and reliable quantitation assay at the femtogram (fg) level. IPC (Internal Positive Control) is included in the kit to evaluate the performance of each PCR reaction.
