Tetramethylrhodamine (TAMRA) Alkyne (5-Carboxytetramethylrhodamine, Propargylamide), 5-isomer

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Other Reactive Probes

The red-fluorescent tetramethylrhodamine (TAMRA) alkyne can be reacted with azides via a copper-catalyzed click reaction. Click chemistry describes a class of chemical reactions that use bio-orthogonal or biologically unique moities to label and detect a molecule of interest using a two-step procedure. The two-step reaction procedure involves a copper-catalyzed triazole formation of an azide and an alkyne. Click reactions have several characteristics: the reaction between the detection moieties is efficient; no extreme temperatures or solvents are required; the reaction product is stable; the ...

Alexa Fluor® 488 Carboxylic Acid, 2,3,5,6-Tetrafluorophenyl Ester (Alexa Fluor® 488 5-TFP), 5-isomer

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Amine-Reactive Fluorophores, Biotins, Quantum Dots, & Other Labels

Tetrafluorophenyl (TFP) esters are an improvement over the succinimidyl ester (SE or NHS-ester) chemistry typically used to attach fluorophores or haptens to the primary amines of biomolecules. Both reactive chemistries produce the same strong amide bond between the dye or hapten and the compound of interest, but TFP esters are less susceptible to spontaneous hydrolysis during conjugation reactions. Alexa Fluor TFP esters are stable for several hours at the basic pH typically used for reactions – far outlasting succinimidyl esters.

Alexa Fluor® 647 C 2 Maleimide

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Thiol-Reactive Fluorophores, Biotins & Other Labels

Conjugates prepared with the thiol-reactive Alexa Fluor 647® C 2 maleimide are spectrally similar to the Cy5 dye, resulting in an optimal match to optical filters for the Cy5 dye. Total fluorescence of secondary antibody conjugates of Alexa Fluor® 647 dye, however, is significantly higher than that of Cy5 conjugates. Unlike the Cy5 dye, Alexa Fluor® 647 dye has very little change in absorption of fluorescence spectra when conjugated to most porteins, oligonucleotides, or nucleic acids, yielding greater total fluorescence at the same degree of substitution.
