Single-cell PCR is an application of PCR technology, which deals with the nucleic acid in single cells rather than in a tissue sample or a pool of homogenous cells. While single-cell amplification has been recognized almost as long as the PCR technology itself, it was not considered a very efficient technique due to uncontrollable circumstances such as the lack of available primers and efficient cell-lysing techniques, which only allowed a small quantity of cell DNA to be amplified.
