WebFeb 3, 2013 · 1 Answer. In this work they find that formaldehyde crosslinking happens by formation of a methylol adduct (due to nucleophilic attack by N or S in case of proteins) in protein which then attacks the DNA or vice-versa. The final crosslink is by a methylene bridge. Formaldehyde can react to amino groups in nucleotides and proteins and form a ... WebThe simplest, most common and versatile techniques for crosslinking or labeling peptides and proteins such as antibodies involve the use of chemical groups that react with primary amines (–NH2).
