Recombinant Human IL4 protein, His-tagged

• Cat.No.: IL4-483H
• Product Overview: Recombinant Human IL4 (P05112) aa. (His25~Ser153) fused with His tag was produced in HEK293F cells.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: His25~Ser153
• Description: The protein encoded by this gene is a pleiotropic cytokine produced by activated T cells. This cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. This gene, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 16.6kDa; Accurate Molecular Mass: 20kDa as determined by SDS-PAGE reducing conditions.
• Endotoxin: <1.0EU per 1ug (determined by the LAL method)
• Purity: > 95%
• Characteristic: Isoelectric point is 9.3.
• Applications: SDS-PAGE; WB; ELISA; IP; CoIP; EMSA; Reporter Assays; Purification; Amine Reactive Labeling
• 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: 200ug/mL
• Storage buffer: 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 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
