How is pcr useful
WebAn antibody against Taq polymerase was used to suppress its enzyme activity by specific antigen – antibody binding at the low temperature, and when PCR started from the denaturing temperature at more than 90°C, the antibody became separated from the enzyme by heat denaturation. Web30 jul. 2015 · RT-PCR is used routinely for detecting certain kinds of leukemia cells that remain after treatment, but its value for more common types of cancer is less certain. The disadvantage is that doctors are not always sure whether having a few cancer cells in the bloodstream or a lymph node means that a patient will actually develop distant …
