Biotin-dPEG®11-NH2 (Biotin-dPEG®11-amine), product number 10196, is one of several biotinylation products offered by Quanta BioDesign, Ltd. that react with carbonyls and carboxylic acids. The product reacts with activated esters (N-hydroxysuccinimide, 2,3,5,6-tetrafluorophenyl) of carboxylic acids. Also, Biotin-dPEG®11-NH2 couples directly to a carboxylic acid using 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) chemistry. Furthermore, the product can react with carbonyl groups (aldehydes or ketones) to form a Schiff base. The Schiff base can be reduced to a secondary amine using sodium cyanoborohydride if additional conjugate stability is necessary.
