One to twenty-four samples can be processed in a single run to isolate free-circulating DNA from fetal-originated DNA in ...

PCR-Machines are based on Polymerase Chain Reaction (PCR) and produce copies of genes exponentially. The PCR cycling reactions are carried out in an automated thermocycler, which is capable of ...

The mixture is then placed in an RT–PCR machine. The machine cycles through temperatures that heat and cool the mixture to trigger specific chemical reactions that create new, identical copies of the ...

The PCR machine increases and decreases the temperature of the sample in automatic, programmed steps. Initially, the mixture is heated to denature, or separate, the double-stranded DNA template ...

A few essential ions and salts The PCR process then uses these ingredients to mimic the natural DNA replication process that occurs in cells. To automate this process, a machine called a ...
