Recombinant Human SLPI Protein, His-tagged

• Cat.No.: SLPI-2704H
• Product Overview: Recombinant Human SLPI Protein (Ser26-Ala132) with a N-His tag was expressed in E. coli.

Specification

• Description: This gene encodes a secreted inhibitor which protects epithelial tissues from serine proteases. It is found in various secretions including seminal plasma, cervical mucus, and bronchial secretions, and has affinity for trypsin, leukocyte elastase, and cathepsin G. Its inhibitory effect contributes to the immune response by protecting epithelial surfaces from attack by endogenous proteolytic enzymes. This antimicrobial protein has antibacterial, antifungal and antiviral activity.
• Source: E. coli
• Species: Human
• Tag: N-His
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 15.4 kDa
  Accurate Molecular Mass: 15 kDa
• Protein length: Ser26-Ala132
• Endotoxin: <1.0 EU per 1µg (determined by the LAL method).
• 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 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
