• General Description: BIOTIN-NHS (Biotin N-hydroxysuccinimide ester) is a reactive derivative of biotin commonly used for bioconjugation, enabling the covalent attachment of biotin to proteins, peptides, or other biomolecules via primary amines. It facilitates affinity labeling, purification, and detection through streptavidin-biotin interactions, as demonstrated in applications such as biotinylated melanotropins, ruthenium complexes, and mRNA cap analogues. Its succinimidyl ester group ensures efficient and selective coupling, making it valuable in biochemical assays, targeted drug delivery, and molecular probes.

Novel non-nucleosidic phosphoramidites for oligonucleotide modification and labeling

10.1016/S0960-894X(97)00278-3

The research focuses on the synthesis of novel non-nucleosidic phosphoramidites and controlled pore glass (CPG) supports, which are based on a cyclohexyl-4-amino-1,1-dimethanol backbone. The purpose of this study was to develop a series of reagents that could be used to label oligonucleotides with biotin and fluorescein at various positions, including the 5'-, 3'-, and internal sites. The researchers aimed to improve the efficiency of synthesis and mimic the stereochemical properties of the natural polynucleotide backbone, while also keeping the reporter groups away from the oligonucleotide chain to enhance hybridization efficiency. The key chemicals used in the process included 3-cyclohexene-1,1-dimethanol, benzoyl chloride, sodium borohydride, BF3-Et2O, hydroxylamine-O-sulfonic acid, biotin-N-hydroxysuccinimide ester (biotin-NHSu), fluorescein-NHSu, and various other reagents for the protection, deprotection, and coupling steps. The conclusions of the research were that these novel biotin, fluorescein, and amino labeled phosphoramidites and CPG supports could be used advantageously for the introduction of multiple reporter groups onto oligonucleotides in a cost-effective and efficient manner, retaining the natural 3-carbon atom internucleotide phosphate distance in DNA/RNA, which does not affect the hybridization and annealing properties of the duplex.
