Catalog Number: (103010-896)
Supplier: Anaspec Inc
Description: AMCA-X, SE is one of the most popular blue fluorescent tagging molecules. It is widely used to label antibodies, proteins and small drug molecules. AMCA-X succinimidyl ester contains a seven-atom aminohexanoyl spacer, the so-called ‘X’ spacer, between the fluorophore and the reactive group. It is well known that the spacer between the fluorophore and the reactive group usually separates the fluorophore from the biomolecule to which it is conjugated, potentially reducing the quenching that typically occurs upon conjugation. In some cases, the ‘X’ spacer allows the dye to be more available for recognition by secondary detection reagents.


Catalog Number: (CAPI21558)
Supplier: Thermo Scientific
Description: Thermo Scientific Pierce SMPT is a long-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form strong (hindered) yet cleavable (reducible) disulfide bonds with cysteine sulfhydryls..

Catalog Number: (103011-048)
Supplier: Anaspec Inc
Description: DABCYL is one of the most popular acceptors for developing FRET-based nucleic acid probes and protease substrates. DABCYL, SE is the amino-reactive form of DABCYL, and widely used to prepare a variety of FRET-based probes that contain DABCYL.


Supplier: Thermo Scientific
Description: Thermo Scientific Pierce Sulfo-SMCC, No-Weigh Format is a water-soluble, amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a medium-length cyclohexane spacer arm (8.3 angstroms).
Supplier: Cytiva
Description: CyDye™ Mono-Reactive Maleimide Fluorescent Dyes are intensely fluorescent and highly water soluble, providing significant advantages over other existing fluorophores.

Supplier: Anaspec Inc
Description: HiLyte™ Fluor594 acid, SE is an amine reactive reagent for labeling peptides, proteins and antibodies.

Catalog Number: (103011-072)
Supplier: Anaspec Inc
Description: QXL® 670 dyes are optimized quenchers for Cy5 and Cy5-like fluorophores such as HiLyte™ Fluor 647.


Supplier: G-Biosciences
Description: The conjugation and modification reactions used to cross-link proteins or couple labels to proteins, such as biotin, enzymes, and fluorescent dyes, require certain conditions, including pH and chemical composition, for optimal conjugation

Catalog Number: (CAPI21650)
Supplier: Thermo Scientific
Description: Thermo Scientific Pierce Sulfo-LC-SPDP is a water-soluble, long-chain crosslinker for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteines.

Supplier: Anaspec Inc
Description: HiLyte™ Fluor 488 acid, SE is an excellent amine-reactive fluorescent labeling dye that generates the protein conjugates far superior to those of fluorescein derivatives such as FITC.

Catalog Number: (103011-236)
Supplier: Anaspec Inc
Description: HiLyte™ Fluor 405 is a blue fluorescent dye with Ex/Em = 404/428 nm, spectrally similar to Alexa Fluor™ 405 and DyLight Fluor™ 405 dyes.


Catalog Number: (103010-934)
Supplier: Anaspec Inc
Description: HiLyte™ Fluor 555 acid, SE is an excellent amine-reactive fluorescent labeling dye that generates the protein conjugates that are only slightly red-shifted compared to those of Cy3 dyes, resulting in an optimal match to filters designed for Cy3 dyes.


Supplier: Biotium
Description: Biotium offers a number of reactive dye formats for labelling proteins, nucleic acids, and other biomolecules with fluorescent dyes. CF® dyes offer advantages in brightness and photostability compared other similar commercial dyes. CF® dyes are available in a number of reactive dye formats for CF® dye colours span the visible and near-infrared spectra.

Supplier: Thermo Scientific
Description: DyLight™ PEGylated dyes display absorption spectra ranging from 550 nm to 783 nm. These reagents fluoresce over a broad pH range, are more intense than Alexa Fluor® or Cy® dyes in many applications and match the output wavelengths of common fluorescence instrumentation. Additionally, the water solubility of the DyLight™ reagents allows a high dye-to-protein ratio without precipitation during conjugation.
