Lectins from Ricinus communis seeds (RCL) have been resolved into three electrophoretically distinct fractions (alpha-RCL, beta-RCL, psi-RCL) by ion exchange chromatography on Watman CM-32 cellulose. The toxicity to mice and antitumor activity against murine lymphoma NK/Ly of pure fractions were compared. Optimal effect was achieved with alpha-RCL, Which possessed the lowest toxicity (1000 micron g/kg) and significant antitumor activity (63% inhibition of tumor growth).
