Conjugation kits for labeling antibodies and proteins

Label your antibody with fluorescent, enzymatic, gold, biotin, avidin or streptavidin labels quickly, efficiently and with 100% antibody recovery using simple protocols.

Our kits can also be used to label other proteins, peptides and biomolecules with free primary amines - find out more in our conjugation kits FAQs. The amount of antibody is optimized for each kit - please consult the kit protocol for specific instructions.
