The ELISA kits listed below target IL4, the symbol for the human gene, interleukin 4, and a member of the IL-4/IL-13 family. The protein encoded by IL4 has a predicted amino acid length of 153, a mass of 17.5 kDa, and a secreted subcellular localization. There are currently 2 reported isoforms, as well as sites of glycosylation. Pathologic involvement is reported in Ischemic stroke. IL4 may also be known by the following names: BCGF-1, pitrakinra, interleukin 4 variant 2, binetrakin, B_cell stimulatory factor 1, and B cell growth factor 1, and BSF-1. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian are available targets of several ELISA kits.
