Tubulin, beta 3 class III (TUBB3), which is the major constituent of microtubules, is primarily Expressed in neurons and is involved in neurogenesis and in axon guidance and maintenance. TUBB3 binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain.

TUBB3 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 473 amino acids (1-450 a.a.) and having a molecular mass of 52.8kDa. TUBB3 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Physical Appearance: Sterile Filtered colorless solution.

Formulation: TUBB3 protein solution (0.25mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 10% glycerol and 1mM DTT.

Stability: Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HAS or BSA).
