APTS

APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of APTS and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff base linkage to a stable carbon-nitrogen bond.

Product Description

APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of APTS and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff base linkage to a stable carbon-nitrogen bond. The multi-anionic nature of the dye makes it ideal for the studies of carbohydrate molecules by high resolution capillary electrophoresis.

    DMSO, Anhydrous

    Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.

    ANTS

    ANTS (8-aminonaphthalene-1,3,6-trisulfonic acid, disodium salt) is a highly negatively charged dye with an amino group that can be coupled to an aldehyde or ketone group to form an unstable Schiff base. The Schiff base is usually chemically reduced by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaB(CN)H3) to form a stable linkage (1).

    CF® Dye Aminooxy

    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.

    Cyanine Dye Aminooxy

    Cyanine dye with an aminooxy reactive group could be used to label a target molecule with an aldehyde or ketone group. Aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent.

    CFDI Hydrazide

    CF®DI dye hydrazide could be used to react with aldehyde or ketone groups from protein carbonylation. CF®DI dyes are designed to match for charge and molecular weight for 2D DIGE platform.

    CF® Dye Hydrazide

    Our CF® dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for neurons, or for gap junction studies.
