HOT-Start PCR
Ø Hot start PCR is to use to minimize
unwanted DNA product.
Ø Major disadvantages is PCR production
of unwanted DNA amplification.
Ø Second step in addition to primer and
tag polymerase. We add specific antibodies to back to polymerase from
annealing.
Ø When temperature raises from
amplification 7200c the specific antibodies detaches from tag
polymerase and amplification being with great specificity.
Ø Modification of polymerase normally
we add some antibody that will coat and being tag polymerase in normal room
temperature is inactive them in room temperature antibody will properly
function. So that tag polymerase can not initiate the polymerase chain
reaction.
Ø As we start increase temperature at
very first of the PCR reaction the temperature can 950c that is call
HOT-start PCR.
Ø Because the HOT-start PCR higher
temperature from beginning.
Ø Then that will inactive all antibody.
Ø Antibody will be degraded so that tag
polymerase. Will free so that the elongate the primer properly.
