Assay principle The assay is based on the cleavage of the yellow tetra- zolium salt MTT to purple formazan crystals by meta- bolic active cells (fig. 1) (6, 7, 35). This cellular reduction involves the pyridine nucleotide cofactors NADH and NADPH (36). The formazan crystals formed are ...
The neutral red uptake assay is based on the ability of viable cells to incorporate and bind the supra vital dye neutral red. This assay is widely usedcytotoxicity assayused for biomedical and environmental applications. The principle behind this is the weak cationic dye penetrates cell membranes ...
The principle premise of the assay is the intrinsic ability of mitochondrial dehydrogenases to reduce MTT to a purple-coloured formazan, which is detected colorimetrically. This renders the assay a choice for many groups studying drug activity in high-throughput screening studies. Therefore, we have ...

Escherichia coli was employed to determine the conditions of assay,which included the feasibility,reaction periods,microbial cell number,the concentration of MTT and so on. It was found that MTT had a high correlation between the values of OD570 and the microbial cell number,which was from 4.9...
These encouraging results along with the debut of a number of proof-of principle, high-current (1-2 MA in 10-100 ns) experiments have prompted consideration of the DZP as a pulsed source of DT fusion neutrons of sufficient strength (S(N) greater-than-or-equal-to 10(19) n/s) to ...
