System Biosciences LLC EXOGLOW MEMBRANE EV LABELING Kit = 25 reactions
Label EV membranes (465 nm excitation/635 nm emission) with a reagent specifically optimized for Exosome labeling. SBI’s new generation of extracellular vesicle (EV) labeling reagents take your EV visualization to new levels of clarity, with low background and high selectivity. Unlike general-purpose labeling reagents that are not optimized for EVs and suffer from high levels of background signal, ExoGlow™-Membrane improves your ability to track and localize EVs by specifically labeling EV membranes with a proprietary fluorescent dye that delivers very low levels of background signal. The result is unmatched EV imaging for more accurate studies (see below for our full range of next generation ExoGlow reagents).
Vector Laboratories Wheat Germ Agglutinin (WGA) Fluorescein-labeled 5 mg
Wheat germ agglutinin (WGA) contains a group of closely related isolectins that bind N-acetylglucosamine (preferentially the dimers and trimers of this sugar) and oligosaccharides containing terminal N-acetylglucosamine or chitobiose, structures common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, cartilage glycosaminoglycans, and glycolipids can also bind WGA. Native WGA also interacts with some glycoproteins via sialic acid residues (see succinylated WGA). This fluorescein-labeled WGA features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 495 nm, emission 515 nm). Supplied as a solution essentially free of unconjugated fluorophores, it is preserved with sodium azide. The recommended inhibiting/eluting sugar is chitin hydrolysate or 500 mM N-acetylglucosamine with salt and/or acid elution.
