Alkali Scientific p Nitrophenyl Phosphoryl Choline, 500 Mg
p-Nitrophenyl Phosphoryl Choline, 500mg, is a high-quality reagent used for studying enzyme-substrate interactions, particularly in the analysis of phospholipase activity. This choline derivative acts as a substrate for enzymes involved in lipid metabolism, and its hydrolysis releases a p-nitrophenol group, which can be detected spectrophotometrically. The 500mg quantity is ideal for small-scale experimental setups in enzymology, pharmacology, and biochemistry. This reagent is essential in the investigation of phospholipase activities, and its use extends to studies in membrane biology, lipid signaling, and drug development.
Medchemexpress LLC Cholic acid 7-sulfate (7-Sulfocholic acid) | 60320-05-0 | 99.9% | 50 MG
Cholic acid 7-sulfate is a selective agonist targeting TGR5 (EC50=0.17 μM) and a ligand for MHC class I-related protein (MR1). As a gut-restricted TGR5 agonist, it binds to TGR5 on enteroendocrine L cells, induces GLP-1 secretion, and improves glucose tolerance in a TGR5-dependent manner. It also acts as an endogenous ligand for MR1, promoting the survival of mucosal-associated invariant T cells (MAIT) and the expression of homeostatic gene signatures, affecting MAIT cell development and function. It is mainly used in the research of diabetes and MAIT cell-related immune regulation.
