Size:
0.1 mg
Protein Information
Protein Name & Synonyms:
IL-4
Target Species:
- Human
Antibody Specifications
Applications:
ELISA (dilution: 0.1, 0.2ug/ml), Functional Assays, Immunohistology - Paraffin, Western Blotting
Concentration (lot specific):
IgG concentration 1.0mg/ml after reconstitution.
Preparation:
Antisera to human IL-4 were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG prepared by affinity chromatography.
Reconstitution:
Reconstitute with 0.1ml distilled water.. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. RayBiotech recommend that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended. NB: For functional studies do not add azide.
Species Reactivity:
Human
Specificity
This product is specific for human IL-4 (Interleukin-4), also known as B-cell stimulatory factor 1, a 129 amino acid pleiotropic cytokine which interacts with multiple cell lineages, including T cells, fibroblasts and hematopoietic cells, and is one of the most important factors involved in B cell IgG1 and IgE class switching.
IL-4 signalling through the IL-4 receptor (IL-4R), under the influence of Stat6, induces the differentiation of CD4+ T cells into Th2 helper cells, which themselves then secrete IL-4 along with IL-5, IL-6, IL-10 and IL-13. Excessive secretion of IL-4 by Th2 helper cells has been linked with allergy and elevated IgE levels.

Storage/Stability
Prior to reconstitution store at +4 °C.
After reconstitution store at -20 °C.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
If stored in this manner, this product is stable for 12 months after receipt.
