Optimization for cell viability assay (MTT assay) - (Feb/01/2011 )
Hi. Im doing a study on effects of certain extracts on cells.
Im using mcf-7 and chang liver cells. im in the optimization stage now. (Im using the MTT assay to determine cell viability)
i did a trpicate for each concentration of cells. but the three reading are not so consistent , for instance one give 1.0 , while the other two reading gives 0.8 .
moreover , a higher reading is observered for 5000 cells compared to 10,000 cells.
im carcking my head over this !
Any suggestion ???
