Can anybody help me out with this:
I'm trying to amplify a 1.5kb region from the origin of replication of a
plasmid from Mycobacterium avium-intracellulare. The primers have been
designed from the published sequence of the origin of replication. The
calculated annealing temperature of the primers is 67 degree C. However i
did not get any results at that temperature. I got an amplicon at 55 degree
C. The size works out to be 0.5kb. What could this be as i should be
getting a 1.5 kb band. How is it possible to get the expected band.
