Antipeptide antibodies were raised in rabbits against a synthetic peptide including the six NH2-terminal amino acids of the pan-specific hemopoietin interleukin 3 (IL 3). Affinity-purified antibody preparations specific for epitopes determined by residues 1 to 6 were immobilized and used as affinity columns. Up to 98% of IL 3 bioactivity in T cell-conditioned medium was depleted by these columns, as was 71 and 74%, respectively, of IL 3 aberrantly produced by the myeloid leukemias WEHI-274.14 and WEHI-3B. IL 3 produced in vivo in WEHI-3B tumor-bearing mice also bound to the anti-1-6 antibody column, up to 70% of the bioactivity being depleted from ascites fluid and up to 84% from the serum. These results suggest that all IL 3 secreted by T cells and the majority of the IL 3 molecules secreted by myeloid leukemias express epitopes determined by residues 1-6 and cannot have the NH2-terminal amino acid sequence initially reported for IL 3. These six NH2-terminal amino acids share similarities with the NH2-terminal amino acids of several other lymphokines, suggesting an important function for this hexapeptide.
