Biotin-14-dATP is a patented dATP analog with biotin attached at the 6-position of the purine base by a 14-atom linker. The long, 14-atom spacer arm allows accessibility to streptavidin for sensitive detection of probe-target hybrids in in situ and filter-based hybridizations. Biotin-14-dATP can be efficiently incorporated into DNA by nick translation in the presence of dCTP, dGTP, and dTTP (1). Biotin-14-dATP can be added to the 3´ end of DNA using terminal deoxynucleotidyl transferase (2). The amount supplied is sufficient for labeling up to 50 µg of DNA by nick translation.
Performance and Quality Testing: Purity is evaluated by reverse-phase HPLC analysis.
