Web1.5-2.0 mM is optimal for Taq DNA Polymerase. Optimal concentration depends on template, buffer, DNA and dNTPs (each has the potential to chelate magnesium) If [Mg 2+] is too low, no PCR product will be seen. If [Mg 2+] is too high, undesired PCR products may be seen. Optimize by supplementing magnesium concentration in 0.5 increments up to 4 … Web18th Aug, 2013. I prefer 3 step method for real-time PCR analysis, although both 2 and 3 steps works because extension/capture at 72C will increase specificity and reduce chance of primer dimer ...
WebThe polymerase chain reaction is a three step cycling process consisting of defined sets of times and temperatures. 3 basic PCR steps include: denaturation step; annealing step; extension (elongation) step. Each of these polymerase chain reaction steps is repeated 30–40 times (cycles). In the course of each cycle, the PCR reaction mixture is ...
