Human placental GH (hGH-V) is a variant of pituitary hGH (hGH-N) synthesized and secreted by syncytiotrophoblasts during pregnancy. It differs from hGH-V by only 13 amino acid residues, which makes difficult a specific measurement of hGH-V without interference from hGH-N. To overcome the analytical difficulties, we produced new high affinity ...
