Recombinant Human IL13 protein, His & T7-tagged

• Cat.No.: IL13-856H
• Product Overview: Recombinant Human IL13 aa. (Leu25~Asn146 (Accession # P35225)) fused with N-terminal His & T7 tag was produced in E. coli cells.

Specification

• Species: Human
• Source: E.coli
• Tag: His&T7
• Protein Length: Leu25~Asn146
• Description: This gene encodes an immunoregulatory cytokine produced primarily by activated Th2 cells. This cytokine is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils. This gene, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL4.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 17.1kDa
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: > 95%
• Characteristic: The isoelectric point is 9.
• Applications: SDS-PAGE; WB; ELISA; IP
• 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.
• Storage buffer: Supplied as lyophilized form in 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% sarcosyl, 5% trehalose, and preservative.
• Reconstitution: Reconstitute in ddH2O.
