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 .

Cat. No.: HY-12591
CAS No.: 103404-75-7
Purity:  99.92%
Synonyms: D-(-)-Luciferin sodium; Firefly luciferin sodium; Beetle Luciferin sodium
D-luciferin sodium is the natural substrate of the enzyme luciferase (Luc) that catalyzes the production of the typical yellowgreen light of fireflies. The 560 nm chemiluminescence from this reaction peaks within seconds, with light output that is proportional to luciferase concentration when the substrate luciferin is present in excess. The luciferase (luc) gene is a popular reporter gene for research and agent screening. Chemiluminescent techniques are virtually background-free, making the luc reporter gene ideal for detecting low-level gene expression. As little as 0.02 pg of luciferase can be reliably measured in a standard scintillation counter. In addition to its role as a reporter of gene expression, luciferase is commonly used in an extremely sensitive assay for ATP . We of er the firefly luciferase (HY-P1004A), luciferin free acid (HY-12591A), as well as its water-soluble sodium salts (HY-12591) and potassium salts (HY-12591B) .

N-[3-(2-Furyl)acryloyl]-Phe-Gly-Gly (FAPGG) is a specific substrate of angiotensin converting enzyme (ACE) with a Ki of 2.546×10 -4 M. It is used as a chromogenic probe for quantitative detection of ACE activity. N-[3-(2-Furyl)acryloyl]-Phe-Gly-Gly can be hydrolyzed by ACE to generate N-[3-(2-furyl)acryloyl]-Phe (FAP) and Gly-Gly, and the ACE inhibitory effect is monitored by photometry. FAPGG competitively binds to the active center of ACE and is a key tool for screening ACE inhibitors such as Captopril (HY-B0368) and Dioscorin. Its reversible mechanism of action supports hypertension research and drug development targeting the renin-angiotensin system .
