Recombinant Human PRB1 Protein, His&GST-tagged

• Cat.No.: PRB1-1978H
• Product Overview: Recombinant Human PRB1 Protein (Gln17-Gln103) with N-His&GST tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: GST&His
• Protein Length: Gln17-Gln103
• Description: This gene encodes a member of the heterogeneous family of basic, proline-rich, human salivary glycoproteins. The encoded preproprotein undergoes proteolytic processing to generate one or more mature peptides before secretion from the parotid glands. Multiple alleles of this gene exhibiting variations in the length of the tandem repeats have been identified. The reference genome encodes the "Medium" allele. This gene is located in a cluster of closely related salivary proline-rich proteins on chromosome 12. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar proteolytic processing.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 38.7 kDa
  Accurate Molecular Mass: 44 kDa
• Purity: > 90%
• 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: 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
• Reconstitution: Reconstitute in ddH2O to a concentration of 0.1-0.5 mg/mL. Do not vortex.
