TIGAR-TAT Recombinant eiwit

TIGAR is a p53-inducible enzyme that catalyzes the hydrolysis of fructose-2-6 bisphosphate (F-2-6-BP) to fructose-6-phosphate and inorganic phosphate. F-2-6-BP is a powerful activator of 6-phosphofructose-1 kinase, the rate limiting enzyme of glycolysis. By lowering the intracellular level of F-2-6-BP, TIGAR expression leads to increased glucose processing via the pentose phosphate pathway, the major cellular source for NADPH. Protein transduction using TAT fusion proteins represents an alternative methodology for introducing transcription factors and other intracellular proteins into primary as well as transformed cells. Recombinant human TIGAR-TAT expressed in E. coli is a 36 kDa protein containing 284 amino-acid residues, including the 271 residues of full-length TIGAR fused to a 13-residue C-terminal peptide containing the TAT transduction domain (GGYGRKKRRQRRR) .

Greater than 95% by SDS-PAGE gel and HPLC analyses.

Room Temp

The lyophilized TIGAR-TAT recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted TIGAR-TAT stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing TIGAR-TAT recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
