| abstract |
The present invention relates to a novel chemical process that provides novel vehicle derivatives that are exceptional 1,2- or 1,3-aminothiol specific reagents for conjugation to unprotected targeted compounds (e.g., polypeptides, peptides, or organic compounds) having or modified to have a 1,2- or 1,3 aminothiol group. The invention further relates to the methods of using novel water-soluble polymer derivatives and conjugates thereof. |
