Will be supplied as "5'-Aminoallyl-2,3'-ddUTP, Li". Unit of measure is "g".
Aminoallyl-modified nucleotides are used for efficient target labeling and a wide variety of dyes and haptens for subsequent post-labeling reactions.
5-Aminoallyl-11-ddUTP is used in 3'-end labeling reactions, serving as a substrate for:
  • Terminal Transferase
  • DNA polymerase I (holoenzyme and Klenow fragment)
  • T4 and T7 DNA polymerase
  • Taq DNA polymerase and reverse transcriptases
Lacking bulky dye groups, aminoallyl-modified nucleotides are incorporated at extremely high and reproducible levels. Reaction of the amine-modified nucleic acid with an excess of amine-reactive dye or hapten results in high and consistent labeling efficiencies, regardless of the dye or hapten chosen. The two-step labeling method eliminates the need to optimize the labeling reaction.
