DIG DNA Labeling and Detection Kit has been used in a variety of hybridization techniques:
- Southern blots
- Northern blots
- Dot blots
- Colony and plaque screening
DIG-labeled hybrids are detected with an anti-DIG-alkaline phosphatase conjugate and the substrates NBT (nitroblue tetrazolium salt) and BCIP (5-bromo-4-chloro-3-indolyl phosphate, toluidinium salt), which give a light blue precipitate.
