Merck, A3553-500G, Acrylamide

Acrylamide functions as a quencher of tryptophan fluorescence. Acrylamide along with bis-acrylamide crosslinks to form polyacrylamide gels, which is used to separate protein and other biomolecules. Bis-acrylamide is essential for crosslinking and acrylamide is required for the polymerization of monomers. Acrylamide alkylates SH groups of cysteine and ε-NH₂ lysine residues of proteins during electrophoresis.
