    Red-β-D-GlcU,CHA

    From: $168 Sizes: 25 mgCatalog #: 10018

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

    Resazurin (alamarBlue™), Sodium Salt

    From: $121 Sizes: 10 mgCatalog #: 10054

    Resazurin (also known as alamarBlue™) is the N-oxide of the fluorescent dye resorufin and is useful for detecting reductive activities in cells. It has been widely used for measuring cell proliferation (1,2) and mitochondrial metabolic activity. Resazurin itself is non-fluorescent until it is reduced to the highly red fluorescent resorufin (λExEm: 563/587 nm).

    Resorufin (High Purity)

    From: $67 Sizes: 100 mgCatalog #: 10062

    High purity resorufin that can be used as a standard for enzyme substrates whose end product is resorufin.

    Rose-β-D-Gal

    From: $153 Sizes: 100 mgCatalog #: 10013

    Rose-β-D-Gal (6-Chloro-3-indoxyl-β-D-galactopyranoside) is a chromogenic substrate for β-galactosidase. The product is similar to X-gal, but generates an intense pink colored precipitate (λmax ~ 540 nm) on enzymatic hydrolysis.

    Rose-β-D-GlcU,CHA

    From: $168 Sizes: 25 mgCatalog #: 10019

    Rose-β-D-GlcU (6-Chloro-3-indolyl-β-D-glucuronide,cyclohexylammonium salt), also known as Salmon-β-D-GlcUA, is similar to X-GlcU, but the product of the substrate is a rose-colored (λmax ~ 540 nm) precipitate, which is easier to detect against the background of plant cells.

    X-β-D-cellobioside

    From: $153 Sizes: 25 mgCatalog #: 10026

    X-β-D-cellobioside (5-Bromo-4-chloro-3-indolyl-beta-D-cellobioside) is a chromogenic substrate for β-cellobiosidase. Enzymatic cleavage of the substrate generates a dark blue-colored precipitate.

    , 10011-1, - 10011-2View allHide

    X-gal (5-Bromo-4-chloro-3-indolyl-β-galactopyranoside) is the most widely used chromogenic substrate for β-galactosidase. Enzyme hydrolysis of the substrate yields a dark blue colored precipitate (maximum absorbance 615 nm).

    X-GlcU, CHA

    From: $122 Sizes: 25 mgCatalog #: 10016

    Alternate name: BCIG. X-GlcU (5-Bromo-4-chloro-3-indolyl-β-D-glucuronide, cyclohexylammonium salt) is a chromogenic β-glucuronidase substrate widely used for monitoring E. coli contamination in food (such as meat, dairy products and shellfish, etc) and water, and for the detection of GUS gene expression in plants.

     
    Product

    X-GlcU, Na

    From: $168 Sizes: 25 mgCatalog #: 10017

    X-GlcU, Na ( 5-Bromo-4-chloro-3-indolyl-β-D-glucuronide, sodium salt), also known as X-GlcA, Na, is similar to X-GlcU, CHA, but has better water solubility.

    XTT

    From: $138 Sizes: 100 mgCatalog #: 10060

    XTT (2,3-Bis-(2-Methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide, disodium salt) is a tetrazolium derivative used widely in cell viability and proliferation testing. The material is readily reduced in viable cells to a highly water-soluble orange colored product (λ= 475 nm).
