SYSTEM BIOSCIENCES LLC EXOGLOW LABELING KITExoGlow™-Vivo EV Labeling Kit (Near IR) = 12 Reactions
Monitor EV trafficking in vivo with the ExoGlow-Vivo EV Labeling Kit (Near IR), a unique dye developed for following Exosomes in animal models and tissues. Visualizing extracellular vesicles (EVs) in cells and organisms has been technically difficult due to the high background from auto-fluorescence in the UV and visible areas of the spectrum and a lack of specificity from the typically lipophilic dyes. SBI’s ExoGlow-Vivo EV Labeling Kit (Near IR) is the first reagent specifically designed to overcome these problems through the use of a proprietary, non-lipophilic dye that emits in the near infrared (NIR) range (excitation at 784 nm; emission at 806 nm). Delivering a level of specificity and sensitivity that takes the guesswork out of tracking EVs in vivo, ExoGlow-Vivo is ideal for EV biodistribution and kinetic studies needed to fully realize the value of EVs in basic research and translational applications.

BROADPHARM BDP 558/568 NHS ester, 25 mg
BDP 558/568 is a borondipyrromethene fluorophore with emission in the yellow part of the spectrum. Its absorption and emission spectra are in similar range as TAMRA, BDP TMR, Cyanine3, and sulfo-Cyanine3. This is an amine reactive NHS ester.
Dojindo Molecular Technologies Inc Biotin-PEAC5-maleimide (10MG), reacts with thiol compounds, such as proteins or peptides with sulfhydryl groups at pH 7-7.5 to create a thioether bond.
Avidin-biotin systems have many applications in immunology and histochemistry. Interactions between avidin and biotin are remarkably strong with dissociation constants on the order of 10-15 M. With an antigen-antibody complex and a biotin-labeled antibody, colorimetric/fluorometric detection of the antigen can be performed using enzymes, fluorophore-labeled avidin or streptavidin. Maleimide biotins react with thiol compounds at a pH of 7-7.5. Maleimide reacts with the sulfhydryl group to create a thioether bond. Unlike other maleimide biotin reagents, Biotin-PE-maleimide can be solubilized in PBS at pH 7.4 to prepare a 2 mM solution without using an organic solvent. The reactivity of maleimide with sulfhydryl groups is higher than that of bromoacetamide, so the required concentration of maleimide biotin is much lower than that of bromoacetamide biotins. Stock solutions of Biotin-PE-maleimide and Biotin-PEAC5-maleimide in DMSO are stable for 1 year at -20°C.
