Biotin-dPEG®4-TFP ester, product number QBD-10009, is an amine-reactive, water-soluble biotin label functionalized with a hydrolytically stable 2,3,5,6-tetrafluorophenyl ester. The single molecular weight PEG4 (dPEG®4) linker is longer than the aminocaproic acid linker of LC-biotin and slightly longer than the two conjugated aminocaproic acid linkers of LC-LC-biotin, allowing for better interaction with the biotin-binding pockets of avidin and streptavidin. Furthermore, unlike traditional LC linkers, the dPEG® linker is flexible and hydrophilic, eliminating biotinylated protein aggregation proteins over time. The TFP ester is more hydrolytically stable than classic NHS esters and has an optimum pH range of 7.5 – 8.5 for conjugating to free amines.
