The maleimide group is one of the most widely used reactive handles in bioconjugation chemistry due to its high selectivity toward thiol groups under mild, aqueous conditions, forming a stable thioether linkage that resists hydrolysis and oxidation. SiR (SiR 6 COOH, 652Ex 674Em) is a far red fluorescent dye that is bright, photostable, and
