Abstract
A polymerase chain reaction (PCR)-based procedure for the detection of TT virus DNA is described. In this method, total nucleic acid extracted from a small volume of serum or plasma is utilized as a template in PCR employing TT virus specific primers designed to highly conserved regions of the virus genome. Additional sensitivity is obtained by carrying out a second round of amplification. Reactions are analyzed by agarose gel electrophoresis, and samples having an ethidium bromide stainable fragment of the appropriate size in the first and/or second amplification are designated as positive. This protocol allows for the rapid and sensitive detection of TT virus in human plasma or serum.
