| Abstract: | Human placental Lactogen (HPL) was isolated from fresh normal human placenta by salting ,precipitating at isoelectric point and ultracentrifugating. The purification was performed by three steps. They are anionexchange chromatography of DEAE-cellulose , sephadex -G - 100 gel filtration and preparative disc electrophoresis. Each step was tested for its immunoactivity by RIA of radiolabelled 125I-HPL. |
