General description

This azadibenzocyclooctyne-biotin derivative is a versatile biotinylation reagent for labeling azide containing molecules or compounds. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions.This dibenzocyclooctyne will react with azide-functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage. Subsequent labeled molecules can be purified using streptavidin or avidin affinity reagents. The PEG spacer makes the overall compound more hydrophilic and allows for greater distance between the reaction site with the azide and the biotin detecting group.

Application

Automate your Biotin tagging with Synple Automated Synthesis Platform (SYNPLE-SC002)

Features and Benefits

More efficient labeling will occur at higher temperatures and with greater excess of biotin reagent. Typical reaction times are up to 4 hours, but longer incubation periods should be used if concentration is low or if low labeling is observed. Product is most efficient when first dissolved in a water miscible organic solvent and then diluted in aqueous reaction buffer when needed. DBCO-PEG4-Biotin is soluble in aqueous buffers up to 0.35 mM.

Polyunsaturated fatty acids (PUFA) are primary targets of free radical damage during oxidative stress. Diffusible electrophilic alpha,beta-unsaturated aldehydes, such as 4-hydroxynonenal (HNE), have been shown to modify proteins that mediate cell signaling (e.g., IKK and Keap1) and alter gene expression
