MTT Cell Proliferation Assay Kit Reference: 10009365-480 Cayman’s MTT Proliferation Assay provides an easy to use tool for studying the induction and inhibition of cell proliferation in any in vitro model. This kit will also allow investigators to screen drug candidates involved in cell cycle regulation. In this assay, MTT is taken up by cells and then reduced to formazan by intracellular NAD(P)H-oxidoreductases.
Glucose Colorimetric Assay Kit Reference: 10009582-2 Cayman’s Glucose Assay provides a simple, reproducible, and sensitive tool for assaying glucose in plasma, serum, and urine. The glucose assay uses the glucose oxidase-peroxide reaction for the determination of glucose concentrations. In this assay, glucose is oxidized to d-gluconolactone with concomitant reduction of the flavin adenine dinucleotide (FAD)-dependent enzyme glucose oxidase. The reduced form of glucose oxidase is regenerated to its oxidized form by molecular oxygen to produce hydrogen peroxide. Finally, with horseradish peroxidase as a catalyst, hydrogen peroxide reacts with 3,5-dichloro-2-hydroxybenzenesulfonic acid and 4-aminoantipyrine to generate a pink dye with an optimal absorption at 514 nm.
Cholesterol Cell-Based Detection Assay Kit Reference: 10009779-2 The mechanism for the movement of cholesterol from intracellular sites to their ultimate cellular destination is an unresolved question of fundamental importance to cell biology and medicine. Thus, defining mechanisms of intracellular cholesterol transport and identifying the cellular factors involved are therefore of great interest. Cayman’s Cholesterol Cell-Based Detection Assay includes filipin III, fixative, and wash buffer in a ready to use format. It provides a simple fluorometric method to study mechanisms and biological factors that regulate cholesterol metabolism or movement within cells. A cholesterol trafficking inhibitor, U-18666A, is included as a positive control.
