WST-8 is a novel, potent and water-soluble tetrazolium dye/salt used for assessing cell metabolic activity. At neutral pH and in the presence of the intermediate electron acceptor. It enhances sensitivity of the WST-8-based assay over the conventional MTS-based assay.
Hyaluronidase (Hyaluronoglucosaminidase; Hyaluronate 4-glycanohydrolase) is a natural enzyme found in high amount in testis, and is able to depolymerize hyaluronic acid by cleaving the glycosidic bonds, used as a local anesthetic additive.
Dansylamide is a novel and reactive fluorescent dye used in biochemistry and chemistry to label substances with the fluorescent dansyl group.
Hexaminolevulinate HCl (also known as hexyl 5-aminolevulinate) is the hexyl ester of 5-aminolevulinic acid (ALA) with photodynamic properties, and has been approved as a fluorescent agent for cystoscopic detection of papillary bladder cancer. As a precursor of photoactive porphorins, hexyl 5-aminolevulinate induces the endogenous production of the photosensitizer protoporphyrin IX (PPIX) which accumulates selectively in […]
MTT (Thiazolyl Blue; Tetrazolium Bromide; Methylthiazolyldiphenyl-tetrazolium bromide), a colorimetric agent, is a cell-permeable and positively charged tetrazolium dye that is widely used to measure cell proliferation. Its mechanism of action is to detect reductive metabolism in cells. MTT is reduced from yellow color to purple formazan in living cells. MTT is used in conjunction with […]
Propidium Iodide is a red fluorescent dye and DNA intercalating agent that can be used to stain cells. Propidium Iodide is used in flow cytometry as a DNA stain to evaluate cell viability or DNA content in cell cycle analysis, and in microscopy to visualise the nucleus and other DNA-containing organelles. Propidium Iodide cannot cross […]
FITC is a novel and potent FITC labeling probe.
Thionin acetate is a metachromic cationic histology dye that has been widely used in biological staining.
Calcein is a novel and potent fluorescent dye.
Sulforhodamine B sodium salt is a novel and potent fluorescent dye.
