SiR-Maleimide Biotin 544 SMILES OC1=CC2=C(C=C1)C1(OC(=O)C3=CC=C(C=C13)C(=O)NCCOCCOCCOCC#C)C1=CC=C(O)C=C1O2 Purity (HPLC)SiR Maleimide is a far red fluorescent probe containg maleimide function group for bioconjugation apploications. 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
