Application
3'-end labeling of oligonucleotides from 14 to 100 nucleotides in length with DIG-11-ddUTP and recombinant Terminal Transferase. DIG-labeled oligonucleotides are used as hybridization probes in all types of membrane-blot applications and in situ hybridization.
Benefits
Fast hybridization kinetics, due to the small size of oligonucleotides Single-stranded probes, no renaturation during hybridization Sequence can be designed according to the experiment Specially suited for in situ hybridization; due to their small size, the oligonucleotides readily diffuse into fixed tissues and cells Contents

Principle
One DIG-ddUTP molecule is added to the 3'-end of oligonucleotides by recombinant Terminal Transferase. This guarantees a very specific and distinct hybridization signal, which is detected by an enzyme-linked immunoassay with anti-DIG-AP antibody conjugate, and a color or chemiluminescence reaction
