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 truncated version (residues 1-179) of c-Jun has been expressed as a fusion with GFP (Green Fluorescent Protein) to act as a substrate for the JNK family of kinases.
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 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).
