1. anti-tumor activity principle
Mtt assay biological activity test, also known as MTT colorimetry, is a kind of method detecting cell survival and growth.MTT Analytic process is with living cells metabolite reducing agent tetrazolium bromide [3-(4,5-dimethyl-2-thiazole)-2,5-diphenyl bromination tetrazole； 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, MTT] based on.MTT is one Plant the dyestuff that can accept hydrogen atom.Dehydrogenase relevant to NADP in living cells mitochondrion intracellular can be by yellow MTT changes into insoluble hepatic first a ceremonial jade-ladle, used in libation (formazon), and dead cell is then without this function.Dissolve with DMSO After formazon, under certain wavelength, measure optical density value by microplate reader, both can quantitatively measure the survival rate of cell.According to The sample inhibitory action to tumor cell is observed in the change of optical density value.
2. anti-tumor activity experiment
