5' Biotin 200 nmol scale, 1 modification

Biotin-labelled oligonucleotides can be used to link the oligonucleotide to streptavidin-protein conjugates, streptavidin affinity columns, or labelled streptavidin. Attachment of a biotin molecule to the 3’ terminus can also be used to prevent 3’ exonuclease digestion and 3’ extension during amplification reactions
