HARS His

Alternative Names: Histidine--tRNA ligase, Histidyl-tRNA synthetase cytoplasmic, HisRS, HARS, HRS, FLJ20491

Histidyl-tRNA synthetase (HARS) is a class II aminoacyl-tRNA synthetase that catalyzes the aminoacylation of tRNAs with their respective amino acids. HARS specifically aids in the synthesis of histidyl-transfer RNA, necessary for incorporating histidine into proteins. In the autoimmune disease polymyositis/dermatomyositis, HARS is often targeted by autoantibodies.

Product Description

Recombinant Human Histidyl-tRNA Synthetase, His Tag is a member of the aminoacyl-tRNA synthetase family, responsible for catalyzing the attachment of histidine to its cognate tRNA molecule during protein synthesis. This enzyme has a molecular weight of approximately 60 kDa and plays a critical role in ensuring the accurate translation of genetic information into functional proteins. The His Tag allows for easy purification and detection of the enzyme in various biochemical assays and research applications.

Storage Instruction

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

Sample Prep Instruction

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
