重组大肠杆菌DnaJ（HSP40）蛋白

产品英文名称：
Recombinant Human Crystallin Beta B1

英文简称:
CRYBB1

中文名称:
重组人晶体蛋白βB1

背景资料:
Crystallins are the main structural proteins of the vertebrate eye lens， where they maintain the transparency and refractive index of the lens. Crystallins are divided into 3 fprotein families， α， β， & γ families. Because lens central fiber cells lose their nuclei during development， these crystallins are prepared and then retained throughout life， making them extremely stable proteins. CRYBB1 is a beta basic group member and undergoes extensive cleavage at its N-terminal extension during lens maturation.

产品描述:
CRYBB1 Recombinant Human produced in E.Coli is a single， non-glycosylated polypeptide chain containing 260 amino acids （1-252 a.a.） and having a molecular mass of 29.1 kDa. The CRYBB1 is fused to 8 amino acid His-Tag at C-terminus and purified by proprietary chromatographic techniques.
