Specificity
This antibody recognises human IGF-II (Insulin-like Growth Factor II), a 67 amino acid mitogenic polypeptide and member of the Insulin gene family, synthesized by various foetal tissues during prenatal development, under the influence of placental lactogen.IGF-II is a growth factor which exhibits both paracrine and autocrine properties and signals by binding to the type 1 and type 2 insulin-like growth factor receptors (type 1 IGFR and type 2 IGFR), and also to the insulin receptor (IR). The availability of IGF-II is dependent upon its attachment to, and release from, various IGF binding proteins (IGFBPs), a relationship which has been investigated in breast cancer research.
