Identification 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.
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 کاملA Small-scale Northern Hybridization with Digoxigenin- labeled RNA Probes from PCR-based Templates
CONTENTS Abstract We describe the use of PCR to generate sense and antisense template DNA for nonradioactive in vitro transcription reactions. The resulting digoxigenin-labeled RNA probes can be used in a small-scale Northern hybridization procedure that is performed in microcentrifuge tubes. This kind of Northern approach is especially useful when the expression of several genes is to be initi...
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 کاملIn situ hybridization with non-radioactive digoxigenin-11-UTP-labeled cRNA probes: localization of developmentally regulated mouse tenascin mRNAs.
An improved method for in situ hybridization was developed in order to identify the tissue-specific expression of messenger RNA (mRNA) for the novel extracellular matrix glycoprotein, tenascin, during mouse development. Non-radioactive RNA probes were generated by incorporating digoxigenin-11-UTP instead of conventional isotopic labels. Hybridization of anti-sense probes to complementary mRNAs ...
