Amplification may have been assisted by the use of a touchdown PCR program and the use of the QIAGEN Multiplex PCR Master Mix, which enhances the likelihood of successful PCR amplification from primers with differing annealing temperatures.
Another strength of our assay is the use of a touchdown PCR covering a range of annealing temperatures (between 62°C and 54°C) to ensure that all the primer pairs hybridise specifically to the template DNA and adequate amounts of PCR product are finally obtained.
As the annealing temperatures of the markers ranged from 47 65°C we opted to use 3 catagories of "touchdown" temperature cycles (see Table 4).
Florida State rallied from a 14-point second-half deficit and used a pair of touchdown passes by E J Manuel and two field goals from Dustin Hopkins to slip past Notre Dame, 18-14, in the Champs Sports Bowl in Orlando, Fla., on Thursday night.
The video recordings were analyzed by playing back the video recordings frame by frame and digitizing the position and orientation of the bird at the point of touchdown using a Matlab (Mathworks, USA) program developed in-house.
To obtain high-quality amplification product, we used the thermocycling profile of touchdown PCR (TD-PCR) (Korbie and Mattick, 2008) with some modifications.
This is probably due to a combination of the high conservation of the C and E domains used to design primers among all steroid nuclear receptors and the low stringency of touchdown PCR procedure that we used.
A new and potentially less complex and lighter way to reduce the shock loads at touchdown is the use of a crushable shield underneath the lander platform.
Instead of giving up and accepting the loss, he makes use of this opportunity and scores a touchdown, placing his team in a comfortable position of winning the game.
For amplification, PCR conditions recommended in [ 15], i. e. 35 cycles of touchdown PCR with the decrease of annealing temperature from 55 to 50 deg C, were used.
