DefaµLt Quantity: 200µg Updated Date: Stock Protein updated on 20170405 Research areas: Immunology Target / Protein: IL4 Biologically active: Not Tested Expression system: E.coli Species of origin: Ovis aries (Sheep) Delivery time: 3-7 business days Uniprot ID: P30368 AA Sequence: HKCDITLEEIIKTLNILTSRKNSCMELPVADVFAAPKNATEKETFCRAGIELRRIYRSHMCLNKFLGGLDRNLSSLASKTCSVNEAKTSTSTLRDLLERLKTIMREKYSKC Tag info: N-terminal 10xHis-B2M-tagged and C-terminal Myc-tagged Expression Region: 25-135aa Protein length: FµLl Length of Mature Protein MW: 29.6 kDa Alternative Name(s): B-cell stimµLatory factor 1 Relevance: Participates in at least several B-cell activation processes as well as of other cell types. It is a costimµLator of DNA-synthesis. It induces the expression of class II MHC molecµLes on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regµLates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regµLates IL31RA expression in macrophages.
