Assay Information
An antirat IL4 coating antibody is adsorbed onto microwells. Rat IL4 present in the sample or standard binds to antibodies adsorbed to the microwells. A biotinconjugated antirat IL4 antibody is added and binds to rat IL4 captured by the first antibody. Following incubation unbound biotin conjugated antirat IL4 antibody is removed during a wash step. StreptavidinHRP is added and binds to the biotinconjugated antirat 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 rat 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 rat IL4 standard dilutions and rat IL4 sample concentration determined.

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.
About
Rats are used to make rat monoclonal anti mouse antibodies. There are less rat- than mouse clones however. Rats genes from rodents of the genus Rattus norvegicus are often studied in vivo as a model of human genes in Sprague-Dawley or Wistar rats.
