Description

Description

Alexa Fluor™ 594 Hydrazide is useful as a cell tracer and as a reactive dye for labeling aldehydes or ketones in polysaccharides or glycoproteins. This version is formatted as a ready-to-use solution that is dissolved in a 200 mM KCl solution and filter sterilized.

Alexa Fluor™ 594 is a bright, red fluorescent dye. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor™ 594 dye is water soluble and pH-insensitive from pH 4 to pH 10. In addition to reactive dye formulations, we offer Alexa Fluor™ 594 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection (learn more).

Detailed information about this AlexaFluor™ hydrazide:

  • Fluorophore label : Alexa Fluor™ 594 dye
  • Reactive group: hydrazide
  • Reactivity: Aldehydes or keytones in polysaccharides or glycoproteins
  • Ex/Em of the conjugate: 588/613 nm
  • Extinction coefficient: 97,000 cm-1M-1
  • Spectrally similar dyes: Texas Red
  • Molecular weight: 758.79

    Cell Tracking and Tracing Applications
    Alexa Fluor™ hydrazides and hydroxlamines are useful as low molecular weight, membrane-impermeant, aldehyde-fixable cell tracers, exhibiting brighter fluorescence and greater photostability than cell tracers derived from other spectrally similar fluorophores. They are easily loaded into cells by microinjection, infusion from patch pipette, or uptake induced by our Influx™ Pinocytic Cell-Loading Reagent. Learn more about cell tracking and tracing.

    Glycoprotein and Polysaccharide Labeling Applications
    The Alexa Fluor™ hydrazides and hydroxlamines are reactive molecules that can be used to add a fluorescent label to biomolecules containing aldehydes or ketones. Aldehydes and ketones can be introduced into polysaccharides and glycoproteins by periodate-mediated oxidation of vicinal diols. Galactose oxidase can also be used to oxidize terminal galactose residues of glycoproteins to aldehydes.

    Hydrazide vs Hydroxylamine
    Hydrazine derivatives react with ketones and aldehydes to yield relatively stable hydrazones. Hydroxylamine derivatives (aminooxy compounds) react with aldehydes and ketones to yield oximes. Oximes are superior to hydrazones with respect to hydrolytic stability. Both hydrazones and oximes can be reduced with sodium borohydride (NaBH4) to further increase the stability of the linkage.
