Description

AA Sequence of recombinant protein: MHGCNDSPLR EIINTLNQVT EKGTPCTEMF VPDVLTATRN TTENELICRA SRVLRKFYFP RDVPPCLKNK SGVLGELRKL CRGVSGLNSL RSCTVNESTL TTLKDFLESL KSILRGKYLQ SCTSMS. Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Rat IL-4. Anti-Rat IL-4-specific antibody was purified by affinity chromatography employing an immobilized Rat IL-4 matrix. Sandwich ELISA: To detect Rat IL-4 by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5-2.0 μg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Rat IL-4 (500-P94Bt) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Rat IL-4. Western Blot: To detect Rat IL-4 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL. When used in conjunction with compatible secondary reagents, the detection limit for Recombinant Rat IL-4 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

Interleukin-4 (IL-4) is a pleiotropic, immune-modulatory cytokine produced by activated T cells, and serves as a ligand for interleukin 4 receptor. IL-4 has been found to have the broadest range of actions. 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 an important role in mediating the immune regulatory signal of IL-4. The IL-4 gene, IL-3, IL-5, IL-13, and CSF2 form a cytokine gene cluster on chromosome 5q. In particular, IL-4 is located in close proximity to IL13 on the chromosome. Further, the IL-4 gene, IL13 and IL5 are found to be coordinated by several long-range regulatory elements over a 120 kilobase range on the chromosome. IL-4 delta 2 is a known splice variant of IL-4.
