Recombinant Human Crystallin Alpha A CRYAA-309H

Cat. No.:	CRYAA-309H
Product Overview:	Recombinant Human CRYA1 protein expressed in E.coli contains 173 (1-173) amino acids and has a molecular mass of 19.9 kDa.
Description:	Alpha crystallins are composed of two gene products; alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein(sHSP also known as the HSP20). They act as molecular chaperones and hold them in large soluble aggregates. These heterogeneous aggregates consist of 30-40 subunits; the alpha-A and alpha-B subunits have a 3:1 ratio, respectively. Two additional function ofa-crystallins are an autokinase activity and participation in the intracellular architecture. The expression of alpha-A is preferentially restricted to the lens cell.
Source:	E.coli.
Formulation:	Liquid. In 20 mM Tris-HCl buffer (pH 7.5) containing 50 mM NaCl, 1 mM EDTA.
Molecular Weight:	19.9 kDa (173aa).
Purity:	> 95% by SDS – PAGE.
Concentration:	1 mg/ml (determined by Bradford assay).
