Ideal for storing prealiquoted master mixes in freezer; just melt waxbead and let it harden over reagents; saves time and ensures reproducibility. Following preparation of PCR cocktail, melt bead and let wax barrier form to keep reagents separate until annealing temperature is reached in cycler.
Features
- Bead is stable at room temperature
- Assures synchronous reaction startup, thereby reducing mis-primes, primer dimers, and premature annealing
- Particularly recommended for complex DNA or cDNA, very low copy number targets, more than 30 thermal cycles, multiple PCR, or RT-PCR
- After thermal cycling reactions, PCR product can remain in tube for later analysis; simply pierce wax layer with pipet tube to remove product
- Hinged caps provide snug seal
