Dyes and Labeling Reagents

This category comprises chemicals for permanent and temporary labeling of organelles, proteins, and other molecules. For example, this includes the covalent linkage of a target protein, such as an antibody, with a fluorescent dye/fluorophore, allowing detection of the target protein in microscopic experiments. For the purpose of detection, proteins can also be coupled with reporter enzymes (e.g. HRP) or radioactive isotopes. To facilitate the purification of a target protein, biotinylation followed by streptavidine affinity binding has proven to be effective.

Calcein blue, AM
Calcein blue, AM

Item number: ABD-22007

It is a cell-permeable version of calcein blue. Upon getting into live cells the weakly fluorescent calcein blue AM is hydrolyzed into calcein blue that has the excitation/emission maxima similar to those of DAPI, Hoechst and AMCA. This exceptional spectral separation from the typical green and red fluorophores...

Fura-2 AM
Fura-2 AM

Item number: Cay14591-1

Fura-2 AM is a membrane permeable, UV light-excitable form of Fura-2 (Cay-19531, Cay-20414). It crosses cell membranes and is converted to Fura-2 via cellular esterases. Fura-2 is a ratiometric fluorescent calcium indicator that can be used to detect calcium in cells. It is a pentacarboxylate that displays...

Phalloidin-iFluor(TM) 594 Conjugate
Phalloidin-iFluor(TM) 594 Conjugate

Item number: ABD-23122

This red fluorescent phalloidin conjugate (equivalent to Alexa Fluor(R) 594-labeled phalloidin) selectively binds to F-actins. Used at nanomolar concentrations, phalloidin derivatives are convenient probes for labeling, identifying and quantitating F-actins in formaldehyde-fixed and permeabilized tissue sections,...

Texas Red-DHPE
Texas Red-DHPE

Item number: ABD-23300

Ex: 595 nm. Em: 615 nm. Soluble in: DMSO. Texas Red(R) DHPE is a phospholipid that is labeled on the head group with the bright, red-fluorescent Texas Red(R) dye (excitation/emission maxima ~595/615 nm). Rhodamine-labeled phospholipids have been used as tracers for membrane traffic during endocytosis and for lipid...

FCB (Fluorescein di-beta-D-cellobioside)
FCB (Fluorescein di-beta-D-cellobioside)

Item number: ABD-14025

This non-fluorescent fluorescein substrate generates the bright fluorescein product that has Ex/Em = 492/514 nm, and can be easily detected with a FITC filter set. In general, fluorescein substrates are much more sensitive than coumarin or nitrophenol-based substrates. This fluorescein substrate is used for...

Calcein Red(TM) AM
Calcein Red(TM) AM

Item number: ABD-21900

Ex: 560 nm. Em: 574 nm. Soluble in: DMSO. Calcein AM is one of the most popular fluorescent probes used for labeling and monitoring cellular functions of live cells. However, the single color of Calcein AM makes it impossible to use this valuable reagent in the multicolor applications. For example, it is impossible...

Item number: ABD-21055

10x50 µg. Ex: 354 nm. Em: 525 nm. Soluble in: DMSO. Although Fura-2 has been widely used as the preferred excitation-ratioable calcium indicator it has certain limitations, e.g., lower sensitivity compared to the single wavelength calcium dyes such as Fluo-8® and Cal-520T. AAT has recently developed Fura-8T to...
