Cyanine3 Maleimide is a bright, orange-fluorescent dye with a maleimide group that selectively reacts with thiol groups in biomolecules. This specificity makes it ideal for labeling proteins, peptides, and other thiolated molecules.
Key Features:
- Bright Fluorescence: Excitation at ~550 nm and emission at ~570 nm provide strong, visible signals.
- Thiol-Reactive Maleimide Group: Enables selective conjugation with cysteine residues in proteins and peptides.
- Versatile Solubility: Soluble in organic solvents like DMSO and DMF; sulfonated versions offer water solubility for labeling sensitive proteins.
Applications:
- Protein and Peptide Labeling: Attaches to thiol groups in cysteine residues for detection and imaging.
- Antibody Labeling: Conjugates with antibodies for use in flow cytometry and fluorescence microscopy.
- Oligonucleotide Labeling: Labels thiol-modified oligonucleotides for nucleic acid research.
Cyanine3 Maleimide is a valuable tool for researchers needing efficient and bright labeling of thiol-containing biomolecules in various biological studies.
We also offer water-soluble Sulfo-Cyanine3 maleimide for the labeling of antibodies and other sensitive proteins.
