Recombinant Active Human TNFSF13B Protein, His-tagged(C-ter)

• Cat.No.: TNFSF13B-319H
• Product Overview: Recombinant Active Human TNFSF13B Protein with His tag (C-ter) was expressed in E. coli.

Specification

• Description: The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFFR. This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells. Alternatively spliced transcript variants encoding distinct isoforms have been identified.

• Source: E. coli
• Species: Human
• Tag: His
• Form: Powder
• Bio-activity: Determined by its ability to induce IL-8 secretion in human PBMCs. The ED50 for this effect is < 0.5 ng/mL.
• AA Sequence: MAVQGPEETVTQDCLQLIADSETPTIQKGSYTFVPWLLSFKRGSALEEKENKILVKETGYFFIYGQVLYTDKTYAMGHLIQRKKVHVFGDELSLVTLFRCIQNMPETLPNNSCYSAGIAKLEEGDELQLAIPRENAQISLDGDVTFFGALKLL
• Endotoxin: Endotoxin level is less than 0.1 EU/μg of the protein, as determined by the LAL test.
• Purity: > 98% (by SDS-PAGE)
• Applications: SDS-PAGE
• Notes: For laboratory research only, not for drug, diagnostic or other use.
• Storage: Lyophilized protein should be stored at -20°C. After reconstitution, aliquot and store at -20°C or -80°C for up to one month. Storage in frost free freezers is not recommended. Avoid repeated freeze/thaw cycles. Suggest spin the vial prior to opening.
• Storage Buffer: PBS (pH 8.0)
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min at room temperature to make sure the protein is dissolved completely.
