Abstract

A novel class of polypeptides of the general formula (F-(Pro).sub.n).sub.m F, wherein F represents a flexible amino acid sequence wherein each amino acid is individually selected from the group consisting of serine, glycine, and threonine, and n is an integer from 4-8 inclusive and m is an integer from 1-4 inclusive, is disclosed. Thses polypeptides are useful in the construction of conjugates between antibodies and peptide toxins. The preparation of such conjugate toxins by linking antibodies to toxin/spacer composites prepared by recombinant techniques is also disclosed.
