IGFBP-rP1 Polyclonal Antibody (Rabbit)

Human IGFBP-rP1 is also known as IGFBP-7, MAC25 protein, PG12 stimulating factor, prostacyclin-stimulating factor and tumour derived adhesion factor. It is a 256 amino acid glycoprotein with structural homology to IGF binding proteins. It binds IGF-I and IGF-II with low affinity and stimulates prostacyclin production and causes cell adhesion.

This IGFBP-rP1 antibody was prepared by immunising rabbits with a 14 amino acid peptide from the Ig-like C2 type domain, linked to diphtheria toxoid. The peptide sequence is unique to IGFBP-rP1. The antibody recognises human IGFBP-rP1 but no other IGF binding protein or related protein. Although the sequence is derived from human IGFBP-rP1, the antibody should recognise IGFBP-rP1 in non-human primates, cattle, sheep and pigs and potentially several other species although this should be experimentally determined. The immunoglobulin fraction was purified by Protein A affinity chromatography. The antibody is suitable for use in immunoassay, immunoblotting and immunohistochemistry.
