Recombinant Human SST protein, His-tagged

• Cat.No.: SST-2618H
• Product Overview: Recombinant Human SST aa. (Met1~Cys116) fused with N-terminal His tag was produced in E. coli cells.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Met1~Cys116
• Description: The hormone somatostatin has active 14 aa and 28 aa forms that are produced by alternate cleavage of the single preproprotein encoded by this gene. Somatostatin is expressed throughout the body and inhibits the release of numerous secondary hormones by binding to high-affinity G-protein-coupled somatostatin receptors. This hormone is an important regulator of the endocrine system through its interactions with pituitary growth hormone, thyroid stimulating hormone, and most hormones of the gastrointestinal tract. Somatostatin also affects rates of neurotransmission in the central nervous system and proliferation of both normal and tumorigenic cells.
• Form: Freeze-dried powder
• Molecular Mass: 18kDa as determined by SDS-PAGE reducing conditions.
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: >95%
• Characteristic: The isoelectric point is 5.6.
• 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°C 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°C for one month. Aliquot and store at -80°C for 12 months.
• Concentration: 200µg/mL
• Storage buffer: 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% sarcosyl, 5%Trehalose and Proclin300.
• Reconstitution: Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex
