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.
A peptide substrate based upon the C-terminal tail of RNA Polymerase II that is a reported substrate for Cyclin Dependent Kinases (CDK7, CDK8 and CDK9).
Specifically optimized for use with the Class III PI3 kinase (PIK3C3 (hVPS34)) and Type III PI4 lipid kinases, this substrate can also be used as a general substrate for the Class I lipid kinases.
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.)
PFB-FDGlu is a cell-permeable substrate used for live cell imaging of GCase activity. It fluoresces green upon cleavage by lysosomal GCase, facilitating specific, single-cell analysis via high-content imaging, flow cytometry, and microscopy.
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.
