Signal Transduction Reagents and Kits
Promega Cell Permeable Inhibitors
LY 294002 is a potent and specific cell-permeable inhibitor of phosphatidylinositol 3-kinases (PI 3-kinases).
Cayman Chemical YM-53601, 182959-33-7, 500 µg
Inhibits squalene synthase activity in rat hepatic microsomes and human Hep-G2 cells (IC50 values of 90 and 79 nM, respectively); inhibits cholesterol biosynthesis in rats reducing both cholesterol and triglyceride levels in plasma
Cayman Chemical Pyruvate Assay Kit, 96 wells
Pyruvate (pyruvic acid) is a key intermediate in cellular metabolic pathways and is derived primarily from glucose via glycolysis. Abnormal blood pyruvate levels are reported in a number of disorders including shock, liver disease, congestive heart failure, diabetes mellitus, thiamine deficiency, and metabolic disorders. Cayman’s Pyruvate Assay provides a fluorescence-based method for quantifying pyruvate in biological samples such as serum, plasma, blood, urine, and saliva. It can also be utilized to determine intracellular and extracellular pyruvate concentrations in cell culture samples.
Cayman Chemical WST-1 Cell Proliferation Assay Kit, 96 wells
Cayman’s WST-1 Proliferation Assay is based on the reduction of tetrazolium salt WST-1 to a soluble formazan dye by electron transport across the plasma membrane of dividing cells. This kit will also allow investigators to screen drug candidates involved in cell cycle regulation.
Cayman Chemical Glycerol Colorimetric Assay Kit, 96 wells
Glycerol is the backbone of triglycerides and an important intermediate in energy metabolism being involved in both oxidative and synthetic processes. The circulating levels of glycerol and free fatty acids are considered to reflect lipolysis and are therefore useful parameters to evaluate in various conditions. The measurement of glycerol is also useful for correction of glycerol interference when measuring triglycerides in reference materials and in serum from patients with elevated glycerol concentrations. Cayman’s Glycerol Assay provides a simple, reproducible, and sensitive tool for measurement of glycerol in plasma and serum. The assay employs a coupled enzymatic reaction system that yields a brilliant purple product with an absorbance maximum at 540 nm.
Cayman Chemical Thiol Detection Assay Kit, 96 wells
The detection and measurement of free thiols (i.e., free cysteine, glutathione, and cysteine residues on proteins) is one of the essential tasks for investigating biological processes and events in many biological systems. Cayman’s Thiol Detection provides a simple, reproducible, and sensitive tool for assaying free thiol content in samples (i.e., plasma, serum, tissue homogenates, cell lysates, and urine). The assay utilizes a proprietary fluorometric detector that reacts with thiol groups to emit a strong fluorescent signal which can be detected using excitation wavelengths between 380-390 nm and emission wavelengths between 510-520 nm.
