TOXIN CONJUGATES Abstract A novel class of polypeptides of the general formula (F-(Pro)n)mF, 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. These 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. |
