商品描述

IL4 is a pleiotropic cytokine produced by activated T cells. IL4 is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which contributes to various overlapping roles of this cytokine and IL13. STAT6, a signal transducer and activator of transcription plays a main role in mediating the immune regulatory signal of this cytokine. IL4, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. IL4, IL13 and IL5 are regulated co-ordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome.
Interleukin-4 Porcine Recombinant produced in E. coli is a non-glycosylated monomer chain containing 110 amino acids and having a molecular mass of 12.7kDa.
IL-4 is purified by proprietary chromatographic techniques.

纯度

Greater than 95.0% as determined by SDS-PAGE.

可溶性

It is recommended to reconstitute the lyophilized IL-4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
