High-fidelity DNA synthesis conditions are those that exploit the inherent ability of polymerases to discriminate against errors. This review has described several experimental approaches for controlling the fidelity of enzymatic DNA amplification. One of the most important parameters to consider is the choice of which polymerase to use in PCR. As demonstrated by the data in Tables 2 and 3, hig...

Amplification of DNA from aged or degraded skeletal remains can be a challenging task, in part due to naturally occurring inhibitors of the polymerase chain reaction. PCR inhibitors may act by inactivating a polymerase itself, or compete with or bind other reaction components, although various polymerases may be differentially susceptible to such insult. In this study, ten thermostable polymera...

conclusions it is suggested that determination of the target genotype by plasma subtyping for choosing the proper antiviral therapy is essential but may result in therapy failure. hcv genotyping in pbmc samples, along with plasma specimens, might be more beneficial. therefore determining the hcv genotype in pbmcs, before beginning the therapy is useful due to the possibility of occult infection...

conclusions: nested pcr as a sensitive chlamydia trachomatis detection test and endocervical specimens has been offered to detect this bacterium in spontaneous abortion. besides, c. trachomatis screening among pregnant women can be suggested to prevent abortion. results: the number of intercourses per week and history of miscarriage can be known as the risk factors of abortion. frequency of c. ...
