A procedure is described for characterization of the proteinic, peptidic, and amino-acidic components of human placental extracts. Four different preparations were analyzed. The first was an extract prepared in our laboratory from fresh on-term placenta. The other three were commercial products obtained by different procedures including autolysis and sterilization. The patterns given by each type of preparation are reproducible and characteristic.
