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. Recombinant Human TIGAR expressed in E. coli is a 29.9 kDa protein containing 269 amino acid residues.

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.
