Protein Labeling Reagents
Aat Bioquest Fluorescein-5-maleimide *CAS 75350-46-8*
Maleimides are among the most frequently used reagents for thiol modification. In most proteins, the site of reaction is at cysteine residues that either are intrinsically present or resulted from reduction of cystines.

Biotium MemBrite™ Fix 488/515 Cell Surface Staining Kit, 500 Reactions
MemBrite™ Fix Cell Surface Staining Kits are designed for covalently staining the surface of live cells to conveniently visualize cell boundaries in immunofluorescence experiments. MemBrite™ Fix are new covalent cell surface stains that react irreversibly with cell surface proteins for staining that can withstand formaldehyde or alcohol fixation, and detergent permeabilization. Unlike lectins such as WGA, which bind specific targets that may vary between cell types, MemBrite™ Fix dyes react widely with cell surface proteins. MemBrite™ Fix staining is rapid and non-toxic to cells, and because MemBrite™ Fix dyes are highly water soluble, they stain cells much more evenly than traditional lipophilic membrane dyes like DiO, DiI, PKH, Vybrant, or CellMask™. This kit has reagents sufficient for 500 labeling reactions. The kit contains 5 vials of MemBrite™ Fix 488/515. Each vial is sufficient for 20 uL of 1000X dye after DMSO reconstitution.
Biotium CF647, Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF647 dye has excitation/emission at 650/665 nm.
Biotium CF770R Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red/near-IR fluorescent CF770R dye has excitation/emission at 770/701 nm.
Biotium CF488A, Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Green fluorescent CF488A dye has excitation/emission at 490/515 nm.
Biotium CellBrite™ NIR750 Cytoplasmic Membrane Dye, 2 mM in DMSO
CellBrite™ NIR Cytoplasmic Membrane Dyes are novel near-infrared carbocyanine dyes for labeling the cytoplasmic membranes of living cells. Due to their long emission wavelengths, near-infrared cell membrane stains can be used to label cells for near-infrared small animal imaging studies for non-invasive imaging of cell migration and cell homing. The dyes have long 18-carbon hydrophobic tails and an additional water-soluble group. These unique chemical structure elements make the dyes easy to dissolve while providing highly stable cytoplasmic membrane staining, unlike traditional carbocyanine dyes like DiI, DiO, and DiR, which are often difficult to dissolve or prone to precipitation during cell staining. CellBrite™ NIR750 has an excitation/emission of 748/780 nm.

AdipoGen 6-JOE
Chemical. CAS 82855-40-1. Formula C23H14Cl2O9. MW 505.26. JOE is a conventional fluorophore predominantly used in automated DNA sequencing. Characterized by an intermediate-wavelength spectra, high quantum yield, and low pH sensitivity in the physiological range. Has a similar absorption and emission spectra to those of rhodamine 6G. Spectral Data lambdaex 520nm, lambdaem550 nm in Buffer pH 12 lambdaex 520nm, lambdaem 548nm in DMSO. JOE possesses an absorbance ˜520 nm and emission ˜550 nm red-shifted compared to those of carboxyfluorescein FAM. The substantial difference in emission wavelengths of FAM and JOE makes them spectrally resolvable and allows simultaneous use of both dyes in multiplex assays. JOE had been applied as a fluorescent label in DNA sequencing, PCR, and LCR amplifications.
Biotium CF568 Hydrazide
Our CF dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for microinjection into cells. Hydrazides also can be used for labeling aldehyde or ketone groups, however, for this application we recommend using the more reactive CF dye aminooxy forms. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
