Sensitivity of digoxigenin and biotin labelled probes for detection of human papillomavirus by in situ hybridisation.
The sensitivity of digoxigenin and biotin labelled DNA probes for the detection of human papillomavirus (HPV) by dot blotting and in situ hybridisation was compared in tissues from cervical, laryngeal, and anogenital neoplasia. Probes were either labelled with digoxigenin by the random primer technique and detected with anti-digoxigenin antibody, or labelled with biotin by nick translation and ...
متن کاملHybridization and detection of digoxigenin probes on RNA blots.
This article describes nonradioactive probing of a Northern blot. The method employs digoxigenin-labeled probes. Antidigoxigenin antibody/alkaline phosphate conjugate, and a chemiluminescent substrate are subsequently used in the detection system.
متن کاملDigoxigenin-labeled probes for the detection of hepatitis B virus DNA in serum.
A nonradioactive hybridization assay for the detection of hepatitis B virus (HBV) DNA in serum with a digoxigenin-labeled probe is described. The probe was sensitive, being able to detect 0.25 pg of homologous HBV DNA, equivalent to 7 x 10(4) genome copies. After extraction of DNA from clinical samples, the probe detected HBV DNA in 11 of 12 hepatitis B e antigen-positive sera and did not react...
متن کاملDetection of pathogenic Yersinia enterocolitica by polymerase chain reaction and digoxigenin-labeled polynucleotide probes.
Yersinia enterocolitica is widespread in nature, but only a few bioserotypes are involved in human infections. Pigs are considered to be the major reservoirs of pathogenic strains. It is essential to have an accurate and rapid method for the detection of pathogenic yersiniae. To achieve this objective, 19-base synthetic oligonucleotide primers were used in a polymerase chain reaction (PCR) to d...
متن کاملIdentification of enterotoxigenic Escherichia coli by colony hybridization with nonradioactive digoxigenin-labeled DNA probes.
Enterotoxigenic Escherichia coli (ETEC) strains were readily identified in pure and mixed cultures with nonradioactive, digoxigenin-labeled DNA probes coding for heat-labile (LTI) and heat-stable (STaI, STaII, and STb) enterotoxins. Digoxigenin-labeled ETEC fragments were more sensitive than and exhibited less nonspecific background contamination than biotinylated ETEC probes.
