Purity > 98% as determined by SDS-PAGE and HPLC. MW: 15.0kDa. Full Length of Mature Protein: 25-153aa. tag-Free. Homo sapiens (Human). Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1.
