  • Consistently, high amounts of primary bile acids as well as sterols were found in their feces. (biomedcentral.com)
  • PCR is fundamental to many of the procedures used in genetic testing and research, including analysis of ancient samples of DNA and identification of infectious agents. (wikipedia.org)
  • Nucleic acid amplification is a foundational process in molecular biology and, as a testament to its utility, new protocols and modifications are being developed constantly. (neb.com)
  • These include molecular, RT-PCR, antigen, and antibody tests approved for hospital and medical settings operating under CLIA guidelines. (labx.com)
