Apexbio Technology LLC Cy3 maleimide (non-sulfonated), 5mg. Cas: MFCD: NA. Labeling of cysteine residues, as well as other thiolated molecules
Cy3 maleimide is a selective and efficient fluorophore dye with low aqueous solubility. This labeling reagent can be used to attach Cy3 fluorophore to proteins and peptides which contain cysteine residues, as well as to other thiolate molecules (such as thiol-containing oligonucleotides). Before the labeling reactions, Cystines should be reduced with TCEP (tris-carboxyethylphosphine). For biomolecule labeling, the labeling reagent has low aqueous solubility, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer. Other sizes are available. Please inqury us for quote.
Abcam NBD- x , SE, 25MG
MW 391.34 Da, Purity >90%. Lipophilic green fluorescent probe for labeling antibodies and proteins. X-spacer provides separation between dye and protein for increased sensitivity and reduced impact on protein function. Functional analog of the dinitrophenol (DNP) hapten. Fluorescence is quenched when bound by anti-DNP antibodies.

Abcam Rhodol, 5MG
MW 331.3 Da, Purity >95%. Highly fluorescent dye useful for labeling oligonucleotide, antibody and protein studies and for the preparation of peptide and esterase substrates. Rhodol is a structural hybrid of fluorescein and rhodamine. It retains the pH-sensitive properties conferred by a phenolic hydroxyl group, but the amine substituent reduces the pKa values. Rhodol exhibits a high extinction coefficient (~70,000 cm-1M-1) and high quantum yield (~0.8-0.9) in aqueous solution, with absorption maxima at approximately 490 nm and emission maxima between 520 and 545 nm. As with fluorescein-based dyes, the fluorescence excitation profiles of rhodol-based dyes are pH dependent, which can be useful for ratiometric pH determinations intracellularly.

Abcam Fluorescein-5-thiosemicarbazide, Fluorescent tag, 50MG
MW 421.43 g/mol, Purity >97%. Fluorescent tag for labeling of cell-surface functional groups (glycophorins). Also used as a probe for detecting protein carbonyl derivatives.

Abcam 3-Dansylaminophenylboronic acid, 50MG
MW 370.2 Da, Purity >98%. Fluorescent probe for cis-diols (sugars). Labels at high pH values on cell surfaces and in glycoproteins, which is used for in vitro carbohydrate determination and HPLC analysis of sugars. Attaches to vicinal diols of sugars, oligosaccharides and certain amino alcohols forming stable cyclic complexes. This agent is also an active site inhibitor for lipases and certain serine proteases. .
