Purity:Purified by Protein A affinity chromatography.
Form:Supplied as a liquid in PBS, 0.09% sodium azide.
Specificity:Recognizes human placental lactogen (epitiope 2). Radioimmunological direct binding studies were performed with 125I-labeled hPL, hGH, hPRL and increasing amounts of INN-hPL-37. In addition, competitive RIA with unlabeled hGH, hPRL and hPL were used for characterization. In competitive RIA cross reactivity with hGH and hPRL was below 1%. Direct binding demonstrated 39% reactivity with hGH but no cross reactivity with hPRL.
