Histidyl-tRNA Synthetase Human Recombinant
Catalog No. ENZ-268
Synonyms:
Histidyl-tRNA synthetase, EC 6.1.1.21, Histidine-tRNA ligase, HisRS, HRS, FLJ20491, JO-1.
Introduction:
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.
Description:
Histidyl-tRNA Synthetase Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain having a molecular mass of 55 kDa.
The Histidyl-tRNA Synthetase is purified by proprietary chromatographic techniques.
Source:
Escherichia Coli.
Physical Appearance:
Sterile Filtered clear solution.
Formulation:
The protein solution contains 150mM NaCl and 10mM sodium phosphate containing 0.1% NaN3 (pH 7.2).
Stability:
Lyophilized Histidyl-tRNA Synthetase although stable at 4°C for 3 weeks, should be stored desiccated below -18°C.
Please prevent freeze-thaw cycles.
Purity:
Greater than 90.0% as determined by both:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Protein content:
Protein quantitation was carried out by using 0.25 - 2.0 mg/ml Bradford assay vs. BSA.
Western Blot:
Strongly reactive with human anti Histidyl-tRNA Synthetase antisera.
Usage:
Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
