There are two forms, which differ in the rate of release of the protecting group. CleanAmp™ Turbo Primers are for fast cycling (<45 minutes) and multiplexed PCR. You will see improved amplicon yield and reduced mis-priming and primer dimer formation. CleanAmp™ Precision Primers are for standard cycling (>45 minutes). You will see improved specificity of amplification, improved limit of detection and the greatest reduction in mis-priming and primer dimer formation.
