Description générale
DIG Oligonucleotide Tailing Kit, 2nd generation employs the enzyme terminal transferase. It catalyzes the addition of digoxigenin (DIG)-11-deoxyuridine triphosphate (dUTP) and deoxyadenosine triphosphate (dATP) to the 3′-OH end of oligonucleotides.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is designed as a safer chemical. The DIG System was established as a sensitive and cost-effective alternative to using radioactivity for the labeling and detection of nucleic acids. There are many available publications that prove the versatility of the DIG System, so use of radio-labeling is no longer the only option for labeling of DNA for hybridization.
Application
DIG Oligonucleotide Tailing Kit, 2nd generation has been used to label oligonucleotide probes in:
- northern blot assay
- in situ hybridization (ISH)
- fluorescence in situ hybridization (FISH)
Caractéristiques et avantages
Tailing of oligonucleotides at the 3′-end with DIG-11-dUTP and recombinant Terminal Transferase. Oligonucleotides are tailed with DIG-dUTP and dATP at an average tail length of 50 nucleotides (tail length range: 10 – 100).
- Very sensitive hybridization probes, due to the incorporation of several DIG-nucleotides
- 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, oligonucleotides readily diffuse into fixed tissues and cells
Conditionnement
1 kit containing 11 components
Principe
DIG-dUTP and dATP are combined at a concentration that gives the highest DIG incorporation into the tail, and optimal spacing of DIG and dATP, to achieve the highest sensitivity in hybridization experiments. DIG-dUTP and dATP are provided as separate solutions to allow greater flexibility in terms of tail length, hapten spacing, and the use of unlabeled nucleotide(s).
