An increase in the selectivity, sensitivity and the suppression of primer dimer formations, fluorescence-based gene expression analyses and gene mutation analyses is accomplished by adding bovine serum albumin to the conventional PCR reaction components. Magnesium chloride concentration is adjusted accurately...
The PCR reaction requires the following components: DNA template- the sample DNA that contains the target sequence. At the beginning of the reaction, high temperature is applied to the original double-stranded DNA molecule to separate the strands from each other. DNA polymerase- a type of enzyme...
The entire PCR cycling procedure is automated and can be finished in a matter of hours. The reaction is controlled by a device known as a thermocycler, which is configured to change the temperature of the reaction every few minutes to enable DNA denaturation and synthesis. Types of PCR Real-...
2.2.2 Components of PCR A conventional PCR reaction mix consists of target DNA, two primers, heat-stable DNA polymerase, deoxynucleotide triphosphates (dNTPs including dATP, dCTP, dGTP and dTTP), and a buffer usually containing Mg2+. Primers are short (20– 30 base pairs) oligonucleotides of...
Template or reaction mixture components are contaminated Re-extract template. Try new reaction mixture. Use filter pipette tips and wear gloves during reaction set-up. Annealing temperature too low Incrementally increase annealing temperature. Primer concentration too high ...
a single copy of dna or a single cell is sufficient for amplification by pcr under ideal conditions. in practice, however, amplification efficiency of a specific template amount is highly dependent upon reaction components and parameter...
