Substrates are laboratory reagents, chemicals, and consumables, and kits used to support or enhance biomedical, pharmaceutical, clinical, food science, environmental, and other research and testing laboratory processes. Products include enzymes, inhibitors, acids, bases, buffers, antibodies, and chromatography supplies.
Store reaction buffers at +4°C or room temperature. Store BACULOSOMES™, the NADPH-regeneration system, and NADP+ at -80°C. Store the Vivid™ substrates and standards at +4°C, protected from light. (For long-term storage, resuspend in organic solvent and keep at -20°C.)
Deubiquitinating enzymes (DUBs) play housekeeping functions by maintaining pools of active ubiquitin, and regulatory function by rescuing specific target proteins from degradation by the proteasome.
Used as substrate for fluorogenic assay of plasma and glandular kallikreins. MilliporeSigma™; Calbiochem™ Z-Phe-Arg-7-amido-4-methylcoumarin, Hydrochloride also acts as substrate for cathepsin B, cathepsin L, and papain.
Specifically optimized for use with the Class I PI3 kinases (PIK3CA, PIK3CB, PIK3CD, and PIK3CG), this substrate consists of lipid vesicles of a 1:19 molar ratio of phosphoinositol-4,5-bisphosphate (PIP2) with phosphotidylserine (PS).
