Recombinant Human Heat Shock 27 kDa Protein 1

• Cat.No.: HSPB1-320H
• Product Overview: Recombinant human Hsp27 was overexpressed in E. coli and purified by conventional chromatography techniques (205 aa, 22.7 kDa).

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Description: Hsp27 (also known as the Estrogen-Regulated 24K protein and hsp28) is a member of the mammalian small heat shock protein family. Hsp27 is expressed constitutively in many tissues and its expression is increased to high levels after various types of stress including elevated temperatures, toxic metals, drugs and oxidants. Also, Hsp27 is phosphorylated in vivo on three phosphorylation sites (Ser15, Ser78 and Ser82) by protein kinases including MAPKAP kinase 2 and the stress-activated protein kinase SAPK2 (p38).
• Formulation: Liquid. In 20 mM Hepesl buffer (pH 7.5) containing 100 mM KCl, 1 mM DTT.
• Molecular Weight: 22.7 kDa (205aa).
• Purity: > 95% by SDS – PAGE.
• Concentration: 1 mg/ml (determined by Bradford assay).
• Endotoxin Level: < 1.0 EU per 1 μg of protein (determined by LAL method).
