Problems solved by technology

However, the kit based on WST-8 detection still has the following defects: the detection solution containing PMS is the same pink color as the culture medium, which may easily cause leakage or overfilling of the detection solution; there is no matching reaction termination reagent, and the reaction time cannot be controlled. It is not suitable for large-scale drug screening; the stability of the detection solution is poor, and it is easy to deteriorate during storage or transportation at high temperature; the reaction time and detection sensitivity need to be further improved

Abstract

The invention discloses a cell proliferation and toxicity detection kit capable of improving detection sensitivity and stability, shortening reaction time, and avoiding leakage of detection liquid. The detection liquid is composed of WST-8, 2-methyl-1 , 4-naphthoquinone, sodium chloride aqueous solution, potassium chloride aqueous solution and calcium chloride aqueous solution, the molar ratio of described WST-8 and 2-methyl-1,4-naphthoquinone is 12~18:1, so The concentrations of the aqueous sodium chloride solution, the aqueous potassium chloride solution and the aqueous calcium chloride solution are 8.6g / L, 0.3 g / L, and 0.28g / L respectively; there is a reaction termination solution, and the reaction termination solution is 0.05 ~ 0.15 mol / L L HCl.

Description

technical field [0001] The invention relates to the technical field of cell biology, in particular to a cell proliferation and toxicity detection kit which can improve detection sensitivity and stability, shorten reaction time, and avoid missed addition of detection solution. Background technique [0002] Cell proliferation and toxicity detection is a basic method for determining the toxicity of substances, evaluating drug safety and cell health, and can also indicate the proliferation activity of tumor cells, the cell proliferation activity of target gene transient / stable cell lines, the overexpression of target genes or RNAi interference. Gene function research plays an important role in drug screening and functional safety research. Therefore, cell proliferation and toxicity detection technology has been widely used in various research fields such as molecular biology, tumor biology, immunology, genetics, pharmacology and pharmacokinetics. [0003] At present, cell proli...
