ABSTRACT:
Rana pipiens eggs are subjected to mechanical processing in the presence of a weakly acidic buffer to produce an extract. The extract is subjected to ion-exchange chromatography and size-exclusion chromatography. Two pharmaceuticals resulting from these steps have activity against certain cancer cells. The amino acid sequences and compositions of two preferred embodiments are disclosed.
