Deoxynucleotide triphosphates (dNTPs) concentration in polymerase chain reaction: effects on DNA amplification / Mohd Fahmi Mastuki
The roles of various reagents in different polymerase chain reaction (PCR) protocols and the necessity to optimize specific PCR applications with respect to deoxynucleotide triphosphates (dNTPs) have been discussed by many researchers. In this study, the concentration of dNTPs influencing PCR amplif...
