Dyes For Labeling Carbonyls & Carbohydrates

Aminooxy reagents (also known as hydroxylamine or aminooxyacetamide) react with aldehydes or ketones to form a stable oxime bond under mild conditions without the use of a reducing agent. Aminooxy can be used to label abasic sites in damaged DNA or carbonyl groups resulting from protein oxidation. They also can be used to label carbohydrates or glycoproteins after oxidation of the carbohydrates to form carbonyl groups. The reaction is fast and can be further accelerated by adding aniline as a catalyst. Aminooxy reagents are superior labeling reagents to hydrazides, because they form more stable linkages.

Hydrazides also react with aldehydes or ketones, but form unstable hydrazone linkages. Hydrazides are non-toxic and highly water soluble, making them useful as fluid phase markers and fixable microinjectable cytoplasmic tracers.

Fluorescent CF® Dye Aminooxy and CF® Dye Hydrazide are available with a wide selection of bright and photostable colors. For 2D DIGE platform, we offer CF®DI reactive dyes, which have matched molecular weight and charge. We also provide a wide selection of classic dyes and biotin in aminooxy and hydrazide forms.

    ANTS

    Sizes: 500 mgCatalog #: 90010

    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).

    Note: Due to operating restrictions related to our COVID-19 response, primary antibody conjugates of R-PE, APC, PerCP, HRP, or AP are temporarily unavailable.

    APTS

    Sizes: 10 mgCatalog #: 90028

    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.
