The Pierce™ Controlled Protein-Protein Crosslinking Kit contains essential crosslinkers, modification reagents and buffers for conjugating antibodies, enzymes and other purified proteins needed as probes.They insert an unbreakable molecular bridge between two proteins with easy-to-control stepwise coupling.

• Reliable non cleavable heterobifunctional crosslinking agent offers proven chemistry, highly stable intermediates and efficient formation of the target conjugate
• Includes disulfide (S-S) reductants and thiolation reagents
• Ellman’s Reagent provides the option to monitor reaction sufficiently

The protocol is logically presented to make the procedure easy for both novices and experts. Chemicals in the kit were selected to allow for the most effective crosslinking. Reagents include a non-cleavable heterobifunctional crosslinking agent for stability and disulfide reductants and thiolation reagents to allow all possibilites of -SH groups to be coupled. A colorimetric reagent is also included to allow for optional reaction efficiency determination.
