Images
Q Li Lee et al investigate the function of outer-membrane-acting peptides in killing Gram-negative pathogens. Cytotoxicity on human cell was determined using lactate dehydrogenase (LDH) cytotoxicity colorimetric assay kit (E-BC-K771-M).
Neither vancomycin nor D-11 affects the viability of human HEK-293 cells.
Detection Principle
Lactate dehydrogenase catalyzes the reaction of lactic acid with NAD+ to produce pyruvic acid and NADH. NADH, under the action of PMS, transfer electrons to WST-8 to produce the yellow product, which has a characteristic absorption peak at 450 nm. Therefore, LDH activity can be quantified by measure the OD value at 450 nm.
