Chemical Structure
BP Fluor 532 maleimide
- CAS No.: 890928-51-5
- Formula:C39H42N4O10S2
- Molecular Weight:790.90
InChIKey: NWYZALSWESAYSY-UHFFFAOYSA-N
SMILES: O=C(C1=CC=C(C2=C(C=C3C(NC(C3(C)C)C)=C4S(=O)(O)=O)C4=[O+]C5=C2C=C6C(NC(C6(C)C)C)=C5S(=O)([O-])=O)C=C1)NCCCCCN7C(C=CC7=O)=O
Biological Activity: BP Fluor 532 maleimide is a photostable, bright yellow-fluorescent dye with pH insensitive emission from pH 4 to pH 10. The excitation of BP Fluor 532 is ideally suited for the frequency-doubled Nd:YAG laser line. BP Fluor 532 dye can be conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates, and is often used for the generation of stable signals in imaging and flow cytometry. Maleimide is the most popular sulfhydryl-reactive group for conjugating the dye to a thiol group on a protein, oligonucleotide thiophosphate, or low molecular weight ligand. The maleimide group specifically and efficiently reacts with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form a stable thioether bond. The resulting conjugates exhibit brighter fluorescence and greater photostability than the conjugates of many other spectrally similar fluorophores.
