Recombinant Human SSB Protein, His-tagged

• Cat.No.: SSB-1240H
• Product Overview: Recombinant Human SSB Protein (Met1-Thr401) with His tag was expressed in CHO.

Specification

• Species: Human
• Source: CHO
• Tag: His
• Protein Length: Met1-Thr401
• Description: The protein encoded by this gene is involved in diverse aspects of RNA metabolism, including binding and protecting poly(U) termini of nascent RNA polymerase III transcripts from exonuclease digestion, processing 5' and 3' ends of pre-tRNA precursors, acting as an RNA chaperone, and binding viral RNAs associated with hepatitis C virus. Autoantibodies reacting with this protein are found in the sera of patients with Sjogren syndrome and systemic lupus erythematosus. Alternative promoter usage results in two different transcript variants which encode the same protein.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 47.8 kDa; Accurate Molecular Mass: 55 kDa
• Purity: > 97%
• Applications: Positive Control; Immunogen; SDS-PAGE; WB.
• Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 centigrade for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months.
• Storage Buffer: PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300.
• Reconstitution: Reconstitute in 10mM PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
