CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. UV-excitable blue fluorescent...

BCIP, toluidine (5-Bromo-4-chloro-3-indoxyl phosphate, p- toluidine salt) is a widely used chromogenic phosphatase substrate, which forms a dark blue (λ_max 615 nm) precipitate on enzymatic hydrolysis. It is often used with the oxidant NBT (nitro blue tetrazolium chloride), which...

High-quality goat anti-digoxigenin (DIG) labeled with red fluorescent CF®568 dye (excitation/emission 562/583 nm). CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. 2mg/mL, 50...

Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a K_d of 1.9 mM. Similar to Fura-2, the excitation wavelength of Mag-Fura-2 undergoes a blue shift from 369 nm to 330 nm. Mag-Fura-2 also responds to Ca 2 but with a significantly lower K_d than Fura-2 for Ca 2...

This product is prepared by labeling highly cross-adsorbed goat anti-rat IgG (H+L) with CF®543 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Orange fluorescent CF®543...

Fluorescent conjugates of Alpha-Bungarotoxin bind to the nicotinic acetylcholine receptor with high affinity, and thus can be used to image the distribution of the receptor at the neuromuscular junctions. Green fluorescent fluorescein (FITC) Alpha-Bungarotoxin has excitation/emission at 494/518 nm.

BactoView™ Dead 560/570 is a novel orange fluorescent DNA dye for no-wash staining of dead bacteria. Unlike traditional dyes like PI that readily stain live gram+ cells, BactoView™ Dead dyes selectively stain dead cells in both gram+ and gram- strains. 500X in water, 100 uL.

MemBrite Fix 543/560 is a orange fluorescent dye that covalently labels the surface of live cells. Unlike lipophilic membrane dyes, MemBrite is well-retained after fixation and permeabilization or methanol fixation.

Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent.

5-CR110-PEO₄ SE (full name: 5-Carboxyrhodamine 110-PEO₄-propionate, succinimidyl ester, single isomer) is an excellent green fluorescent rhodamine dye for labeling amines. The dye has better solubility than the parent dye 5-CR110 SE and its long PEG spacer should reduce any...

Mix-n-Stain™ Antibody Labeling Kits are a revolutionary antibody labeling technology that allows you to label your antibody with one of our superior CF® dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. CF® dyes...

This product is prepared by labeling highly cross-adsorbed donkey anti-rat IgG (H+L) with CF®640R dye. 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...
