Anti-IL-4 Antibody - BSA and Azide free (A283925)

Anti-IL-4 Antibody - BSA and Azide free

Rabbit polyclonal antibody to IL-4.

This antibody recognises 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 haematopoietic 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.

1 mg/ml after reconstitution.

Reconstitute with 0.1 ml of distilled water. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Gently mix after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended. For functional studies do not add sodium azide.

Supplied in Phosphate Buffered Saline.

Lyophilized: Store at -20°C. Reconstituted: Store undiluted at -20°C, avoid freeze / thaw cycles. Storage in frost free freezers is not recommended. Should this product contain a precipitate we recommend microcentrifugation before use.
