1704234-1	1990	A highly specific monoclonal antibody (anti-AFP) against alpha-fetoprotein (AFP) was linked to N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP) to form conjugates which were purified with a protein A-sepharose CL-4B affinity column.

1704234-3	1990	The immunotoxin, anti-AFP-abrin-A conjugate, which was also purified with a protein A-sepharose CL-4B affinity column, had a molecular weight of 180,000 and had 80% antigen-binding activity that of anti-AFP activity and 92% toxicity of abrin-A chain.
