| Polymerase chain reaction products were examined by agarose gel electrophoresis and ethidium bromide staining. |
| Presence of oncogenic HPV types 16 and 18 DNA was done by polymerase chain reaction. |
| Genotypes were obtained by automated sizing of fluorescently tagged polymerase chain reaction amplification products. |
| It can protect the polyunsaturated fatty acids in cell membranes from the autocatalytic chain reaction of lipid peroxidation. |
| When high concentrations of these pollutants accumulate and interact with sunlight, a chain reaction occurs. |
| We analyzed gene mutations in patients who died of thrombotic events, using multiplex allele-specific polymerase chain reaction amplification. |
