CATALOGUE NUMBER

ENZ-001

SYNONYMS

Histidyl-tRNA synthetase cytoplasmic, Histidine--tRNA ligase, HisRS, HARS, HRS, FLJ20491.

INTRODUCTION

Histidyl-tRNA synthetase (HARS) functions to catalyze the aminoacylation of tRNAs by their corresponding amino acids. HARS is a member of the class II family of aminoacyl-tRNA synthetases. HARS is responsible for the synthesis of histidyl-transfer RNA, which is vital for the incorporation of histidine into proteins. HARS is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis.

DESCRIPTION

HARS Human Recombinant fused with a 23 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 532 amino acids (1-509 a.a.) and having a molecular mass of 59.4kDa. The HARS is purified by proprietary chromatographic techniques.

SOURCE

Escherichia Coli.

PHYSICAL APPEARANCE

Sterile Filtered colorless solution.

FORMULATION

The HARS solution (1mg/ml) contains 20mM Tris-HCl buffer(pH 8.0), 10% glycerol, 
1mM DTT and 0.1M NaCl.

STABILITY

Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time. 
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

PURITY

Greater than 95.0% as determined by SDS-PAGE.
