With the ever-growing use of multiplex assays in research, therapeutics, and diagnostics, the need to conjugate antibodies to dyes, enzymes, and other materials is increasing. While there are many challenges to overcome regarding conjugation, the largest hurdle is maintaining antibody activity after conjugation. To combat these conjugation challenges, AlphaThera developed a conjugation system that utilizes a small adapter protein to label antibodies quickly and site-specifically, resulting in antibodies that maintain their activity post conjugation. The adapter protein contains a customizable C-terminal region that can be modified to contain diverse labels including fluorescent dyes, click-chemistry, drugs, and epitope tags.
