Comparison of Immobilon-N membrane and other membranes for the detection of HIV-1 genome in high risk patients using PCR.
The polymerase chain reaction (PCR) was used for detection of the HIV-1 genome from the peripheral blood lymphocytes of high risk patients. The gag regions of HIV-1 (SK38-SK39) were chosen to amplify viral DNA and the amplified products were spotted onto membrane filters and hybridized with a 32P-labeled SK19 probe. Nitrocellulose, nylon and polyvinylidene difluoride (PVDF) membrane filters were used and compared in dot-blot hybridization. PVDF (Immobilon-N, trade name) filter membranes were demonstrated to be the best membranes on the basis of hybridization data and showed a stronger signal on autoradiograms than the other two types (nitrocellulose and nylon).
