Recombinant Human SEMG2 Protein, His-tagged

• Cat.No.: SEMG2-2683H
• Product Overview: Recombinant Human SEMG2 Protein (Leu261-Lys500) with a N-His tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Leu261-Lys500
• Description: The secreted protein encoded by this gene is involved in the formation of a gel matrix that encases ejaculated spermatozoa. Proteolysis by the prostate-specific antigen (PSA) breaks down the gel matrix and allows the spermatozoa to move more freely. The encoded protein is found in lesser abundance than a similar semenogelin protein. An antibacterial activity has been found for a antimicrobial peptide isolated from this protein. The genes encoding these two semenogelin proteins are found in a cluster on chromosome 20.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 3.7 kDa
• Endotoxin: <1.0 EU per 1µg (determined by the LAL method).
• 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 PBS or others.
