Conservation in sequence and affinity of human and rodent PDGF ligands and receptors.


Platelet-derived growth factor (PDGF) consists of two chains, PDGF-A and -B, which activate as homo- or heterodimers two receptors, alpha and beta. To test PDGF function in vivo we have generated neutralizing monoclonal antibodies. When analyzed with rat PDGFs only antibodies raised against human PDGF-AA showed cross-species activity. This correlated with… (More)
