Heterobifunctional crosslinking reagents based on NHS-ester and phenyl azide or diazirine photoreactive groups for two-stage conjugation of amine-containing proteins and other biomolecules with any nearest-neighbor interaction partners.
Very short to mid-length (3.9 to 13.5A), amine-to-anything crosslinkers; NHS-ester and diazirine reactive groups; photoactivate with UV light (Amax 330 to 370nm).
Long (18.2A) amine-to-anything crosslinker; composed of Sulfo-NHS-ester and nitrophenyl azide reactive groups; photoactivates with UV light (Amax 320 to 350nm).
