WC4 Antibody (CC57) is a high quality monoclonal WC4 antibody (also designated WC4 antibody) suitable for the detection of the WC4 protein of ovine, caprine and bovine origin. WC4 Antibody (CC57) is available as both the non-conjugated anti-WC4 antibody form, as well as multiple conjugated forms of anti-WC4 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. CD19 is a transmembrane glycoprotein that contains two extracellular immunoglobulin-like domains. CD19 is selectively expressed on the cell surface of B-lymphocytes, where it activates intracellular signaling cascades involving both Ras and phosphatidylinositol 3-kinase pathways. Activation of CD19 results in cross-linking of the membrane protein immunoglobulin chains and the subsequent association with Src family protein tyrosine kinases (PTK). Expression of CD19 is continuous throughout B-cell development and through terminal differentiation of B-cells into plasma cells. CD19 forms functional complexes with B-lymphocyte surface proteins, including integrin b1, CD21 and CD81, which are involved in regulating B-cell development. Bovine WC4 (workshop cluster 4) may be a homolog of CD19, and has been observed in B-cells, tonsil and mesenteric lymph node.
