Recombinant Human CTRB1 protein, His & T7-tagged

• Cat.No.: CTRB1-1165H
• Product Overview: Recombinant Human CTRB1 aa. (Ile34~Ala261 (Accession # P17538) fused with N-terminal His & T7 tag was produced in E. coli cells.

Specification

• Species: Human
• Source: E.coli
• Tag: His&T7
• Protein Length: Ile34~Ala261
• Description: This gene encodes a member of the serine protease family of enzymes and forms a principal precursor of the pancreatic proteolytic enzymes. The encoded preproprotein is synthesized in the acinar cells of the pancreas and secreted into the small intestine where it undergoes proteolytic activation to generate a functional enzyme. This gene is located adjacent to a related chymotrypsinogen gene. This gene encodes distinct isoforms, some or all of which may undergo similar processing to generate the mature protein.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 27.9kDa.
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: >95%
• Characteristic: The isoelectric point is 6.1.
• 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 5% trehalose, 0.01% sarcosyl.
• Reconstitution: Reconstitute in sterile PBS, pH7.2-pH7.4.
