Recombinant Human NARS protein, His & T7-tagged

• Cat.No.: NARS-8205H
• Product Overview: Recombinant Human NARS aa. (Met1~Arg330 (Accession # O43776)) fused with N-terminal His & T7 tag was produced in E. coli cells.

Specification

• Species: Human
• Source: E.coli
• Tag: His&T7
• Protein Length: Met1~Arg330
• Description: Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. Asparaginyl-tRNA synthetase is localized to the cytoplasm and belongs to the class II family of tRNA synthetases. The N-terminal domain represents the signature sequence for the eukaryotic asparaginyl-tRNA synthetases.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 41.2kDa.
• Endotoxin: <1.0EU per 1ug (determined by the LAL method)
• Purity: >90%
• Characteristic: The isoelectric point is 8.3.
• Applications: SDS-PAGE; WB; ELISA; IP.
• Stability: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
• Storage Buffer: Supplied as lyophilized form in 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% sarcosyl, 5% trehalose, and preservative.
• Reconstitution: Reconstitute in sterile ddH2O.
