Protein cross-linking and modification reactions often required carefully controlled reaction conditions as some buffers will interfere with coupling and modification reactions. For example, Tris buffers will interfere with amine coupling reactions.
G-Biosciences offers a selection of optimized buffers designed for specific reactions.
G-Biosciences also offers a reactor system, Tube-O-Reactor™, that is ideal for protein cross-linking and modification reactions.
TNBS (2,4,6-trinitrobenzene sulfonic acid) is a highly sensitive and rapid chemical used to quantitate the free amino groups. The reaction of TNBS with primary amines generates a highly chromogenic product that can be readily measured at 335nm.
Supplied as a 1% solution.
