Recombinant Human CLDN18 Protein, His-tagged

• Cat.No.: CLDN18-794H
• Product Overview: Recombinant Human CLDN18 Protein (Cys196-Val261) with His tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• ProteinLength: Cys196-Val261
• Description: This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions. This gene is upregulated in patients with ulcerative colitis and highly overexpressed in infiltrating ductal adenocarcinomas. PKC/MAPK/AP-1 (protein kinase C/mitogen-activated protein kinase/activator protein-1) dependent pathway regulates the expression of this gene in gastric cells. Alternatively spliced transcript variants encoding different isoforms have been identified.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 10.9 kDa; Accurate Molecular Mass: 11 kDa
• Purity: > 95%
• 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.
