Red-Beta-D-GlcU (5-Bromo-6-chloro-3-indolyl-beta-D-glucuronide,cyclohexylammmonium salt), also known as Magenta-beta-D-GlcA; is similar to X-GlcU, but the product of the substrate is a red (λ_max 565 nm) precipitate, which is easier to detect against the background of plant cells....

BCIP Red (5-Bromo-6-chloro-3-indoxyl phosphate, p -toluidine salt ) is a derivative of BCIP. While BCIP yields a blue precipitating product, BCIP Red produces a red (λ_max 565 nm) colored precipitate.

Amine-reactive form of 5-carboxyrhodamine 6G single isomer. &lamba;_Ex/&lamba; _Em(MeOH) = 520/546 nm Orange red solid moderately soluble in DMSO Store at -20°C and protect from light C₃₁H₂₉ClN₃O₇ MW: 555.6

Biocytin hydrazide is an aldehyde-fixable cellular tracer that can be introduced into cells by microinjection. Biocytin hydrazide can also be used to label glycoproteins or other carbohydrate molecules.    White solid soluble in DMSO   Store desiccated at 4°C  ...

This kit provides a two-color fluorescence staining on both live bacteria (green) and dead bacteria (red) using two probes DMAO and EthD-III. DMAO is a green-fluorescent nucleic acid dye which stains both live and dead bacteria. EthD-III is a red-fluorescent nucleic acid dye that selectively stains...
