Assay Information
An antimouse IL4 coating antibody is adsorbed onto microwells. Mouse IL4 present in the sample or standard binds to antibodies adsorbed to the microwells. A biotinconjugated antimouse IL4 antibody is added and binds to mouse IL4 captured by the first antibody. Following incubation unbound biotin conjugated antimouse IL4 antibody is removed during a wash step. StreptavidinHRP is added and binds to the biotin conjugated antimouse IL4 antibody. Following incubation unbound StreptavidinHRP is removed during a wash step, and substrate solution reactive with HRP is added to the wells. A coloured product is formed in proportion to the amount of mouse IL4 present in the sample or standard. The reaction is terminated by addition of acid and absorbance is measured at 450 nm. A standard curve is prepared from 7 mouse IL4 standard dilutions and mouse IL4 sample concentration determined.

Test
ELISA Enzyme-linked immunosorbent assays Code 90320007 SNOMED,Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
Gene
Interleukin 4 (IL4) is a cytokine that induces differentiation of naive helper T cells (Th0 cells) to Th2 cells. It is used for dendritic and T cell therapy. Upon activation by IL-4, Th2 cells subsequently produce additional IL-4 in a positive feedback loop. The cell that initially produces IL-4, thus inducing Th0 differentiation, has not been identified, but recent studies suggest that basophils may be the effector cell. It is closely related and has functions similar to Interleukin 13. Recombinant, GMP rec. E. coli interleukin-4 for cell culture supplied by GENTAUR. Free samples on request.
