alexa fluor® 568 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® 568 is a bright, red fluorescent dye. used for stable signal generation in imaging and flow cytometry, alexa fluor® 568 dye is water soluble and ph-insensitive from ph 4 to ph 10. in addition to reactive dye formulations, we offer alexa fluor® 568 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® 568 dye • reactive group: hydrazide • reactivity: aldehydes or keytones in polysaccharides or glycoproteins • ex/em of the conjugate: 576/599 nm • extinction coefficient: 86,000 cm-1m-1 • spectrally similar dyes: rhodamine red • molecular weight: 730.74
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 ourinflux™ pinocytic cell-loading reagent. it is designed to be loaded into cells by microinjection or infusion from patch pipette.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.
we’ll make a custom conjugate for you if you can’t find what you’re looking for in our online catalog, we’ll prepare a custom antibody or protein conjugate for you. ourcustom conjugation serviceis efficient and confidential, and we stand by the quality of our work. we are iso 9001:2000 certified.
