Recombinant Human MSMB protein, His & S-tagged

• Cat.No.: MSMB-7959H
• Product Overview: Recombinant Human MSMB aa. (Asn19~Ile114 (Accession # P08118)) fused with N-terminal His & S tag was produced in E. coli cells.

Specification

• Description: The protein encoded by this gene is a member of the immunoglobulin binding factor family. It is synthesized by the epithelial cells of the prostate gland and secreted into the seminal plasma. This protein has inhibin-like activity. It may have a role as an autocrine paracrine factor in uterine, breast and other female reproductive tissues. The expression of the encoded protein is found to be decreased in prostate cancer. Two alternatively spliced transcript variants encoding different isoforms are described for this gene. The use of alternate polyadenylation sites has been found for this gene.
• Source: E. coli
• Species: Human
• Tag: His&S
• Form: Freeze-dried powder
• Molecular Mass: 22kDa as determined by SDS-PAGE reducing conditions.
• Protein length: Asn19~Ile114
• Endotoxin: <1.0EU per 1ug (determined by the LAL method)
• Purity: >95%
• Characteristic: The isoelectric point is 5.6.
• 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 PBS, pH7.4, containing 1mM DTT, 5% trehalose, 0.01% sarcosyl and preservative.
• Reconstitution: Reconstitute in sterile PBS, pH7.2-pH7.4.
