Cat. No.: HY-15924
CAS No.: 298-93-1
Synonyms: MTT; Thiazolyl Blue Tetrazolium bromide; Methylthiazolyldiphenyl-tetrazolium bromide
Thiazolyl Blue (MTT) is a cell-permeable and positively charged tetrazolium dye that is used to detect reductive metabolism in cells. Thiazolyl Blue is taken up by cells through the plasma membrane and then reduced to formazan by intracellular NAD (P) H-oxidoreductases. Thiazolyl Blue is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis .

Synonyms: CPRG
Chlorophenol red-β-D-galactopyranoside (CPRG) is an efficient and sensitive chromogenic substrate for β-galactosidase (HY-P2869), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside itself appears pale yellow. When it is specifically hydrolyzed by β-galactosidase, it releases chlorophenol red. The released chlorophenol red turns purple-red under alkaline or neutral pH conditions. This color change from yellow to red can be quantitatively detected at wavelengths of 540-572 nm using visible spectrophotometry .

Cat. No.: HY-D0259
CAS No.: 16423-68-0
Synonyms: Erythrosin extra bluish; Tetraiodofluorescein disodium
Research Areas:  

Infection

Erythrosine B (Erythrosin extra bluish; Tetraiodofluorescein) is a visible red dye and insecticide with colorimetric and fluorescent properties. Erythrosine B serves as a membrane-impermeant live-cell dye for Gram-positive and Gram-negative bacteria, primarily staining dead cells with damaged plasma membranes. Erythrosine B exhibits photosensitive larvicidal toxicity against Culex pipiens quinquefasciatus larvae. Erythrosine B is used in live/dead bacterial assays in colorimetric and fluorescent measurements for low-, medium-, and high-throughput experiments, as well as in research related to mosquito-borne diseases and food coloring .

Cat. No.: HY-W011654
CAS No.: 5094-33-7
Synonyms: 4-Aminophenyl-beta-D-galactopyranoside, 98%
4-Aminophenyl-β-D-galactopyranoside, 98% is a highly efficient substrate for β-galactosidase. It is specifically hydrolyzed by this enzyme to release galactose and electroactive p-aminophenol. 4-Aminophenyl-β-D-galactopyranoside, 98% is widely used in colorimetric and electrochemical assays for detecting β-galactosidase activity and determining enzyme kinetics, such as in biosensing fields including cellular senescence, pathogen and contaminant detection. In addition, since β-galactosidase is often overexpressed in primary ovarian cancer, 4-Aminophenyl-β-D-galactopyranoside, 98% can also be applied to related research on primary ovarian cancer .
