The QuantiSir™ Specific Gene Knockdown Quantification Kit For Cell Proliferation series, offering a flexible choice of different kits used for measuring the knockdown of 45 common genes related to cell proliferation, is part of Epigentek's advanced gene knockdown assay system to quantify gene knockdown induced by siRNA or antisense oligonucleotide at the protein level in cultured cells or tissues. The kit offers a highly more highly convenient process than traditional methods such as Northern blot, quantitative RT-PCR, and Western Blot. The kit addresses and corrects traditional problems such as the decrease in the amount of a specific mRNA not typically correlating well with protein levels present in the cell, and the lack of ability to discriminate between samples in which the differences in protein levels are minimal. The kit has the following advantages:
Principle & ProcedureThe QuantiSir™ Specific Gene Knockdown Quantification Kit For Cell Proliferation is specifically designed for quantifying gene knockdown induced by siRNA or antisense oligonucleotide at the protein level in the cultured cells or tissues. In the assay, the cell lysates containing the targeted protein are stably spotted on the specifically treated microwells with a unique protein capture buffer. The spotted protein can then be recognized with the target-specific antibody and colorimetrically measured through detection antibody-chromogen reaction system.
