Recombinant Human HARS, GST-tagged

• Cat.No.: HARS-13669H
• Product Overview: Recombinant Human HARS protein, fused to GST-tag, was expressed in E.coli and purified by GSH-sepharose.

Specification

• Species: Human
• Source: E.coli
• Tag: GST
• Protein Length: 1-282a.a.
• Description: Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a cytoplasmic enzyme which belongs to the class II family of aminoacyl-tRNA synthetases. The enzyme is responsible for the synthesis of histidyl-transfer RNA, which is essential for the incorporation of histidine into proteins. The gene is located in a head-to-head orientation with HARSL on chromosome five, where the homologous genes share a bidirectional promoter. The gene product is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis. Several transcript variants encoding different isoforms have been found for this gene.
• Storage: The protein is stored in PBS buffer at -20℃. Avoid repeated freezing and thawing cycles.
• Storage Buffer: 1M PBS (58mM Na2HPO4,17mM NaH2PO4, 68mM NaCl, pH8. ) added with 100mM GSH and 1% Triton X-100,15%glycerol.
