Rabbit anti Mouse Interleukin-4 antibody recognizes mouse interleukin-4 (IL-4), also known as B-cell stimulatory factor 1, a 120 amino acid pleiotropic cytokine cleaved from a 140 amino acid precursor which interacts with multiple cell lineages, including T cells, fibroblasts and macrophages (Crawford et al. 1987).

Interleukin-4 is one of the most important factors involved in B cell IgG1 and IgE class switching (Winter et al. 1987). IL-4 acts as a regulator of low affinity Fc receptor for IgE (CD23) expression on both lymphocytes and monocytes (Miyajima et al. 1991, Hudak et al. 1987). IL-4 acts through binding to it's cognate receptor CD124, a receptor which also binds the related cytokine IL-13.

Interleukin -4 plays an important role in the alternative activation of murine macrophages as indicated by the ability to potently up-regulate the expression and activity of CD206, the macrophage mannose receptor (Stein et al. 1992).

Product Details

Target Species
Mouse
Product Form
Purified IgG - lyophilised
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. Bio-Rad 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.
Antiserum Preparation
Antisera to mouse IL-4 were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG was prepared by affinity chromatography.
Buffer Solution
Phosphate buffered saline
Preservative Stabilisers
None present
Immunogen
Recombinant mouse IL-4
Approx. Protein Concentrations
IgG concentration 1.0 mg/ml after reconstitution.

Storage Information

Storage
Prior to reconstitution store at -20oC. Following reconstitution store at -20oC.

This product should be stored undiluted.

Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Guarantee
6 months from date of reconstitution.
