This advanced biotinylation reagent contains UV-traceable benzophenone moiety that has absorption maximum at 350 nm. Two surrounded hydrophilic arms enhance water solubility, reduce the tendency of some proteins to aggregate/precipitate during biotinylation, and improve conjugate yield at moderately-to-higher biotin loads. After biotinylation, the conjugate’s absorbance at 280 nm and 350 nm is used to rapidly and quantitatively measure the level of biotin incorporation. UV-TracerTM Biotin-Maleimide reagent improves labeling reproducibility and yield at higher biotin loads for maximum assay sensitivity and robustness.
