PURPOSE To determine whether human conjunctival epithelium expresses any of the human mucin genes designated MUC2 through MUC7. METHOD Northern blot analysis was performed using total RNA isolated from surgically removed conjunctival tissues. Complementary DNA or oligonucleotides to the tandem repeat region of each mucin gene were labeled and hybridized to conjunctival RNA. In situ hybridizat...
Because of the allelic variations within the M protein gene (emm gene) of group A streptococci, reliable typing of this important human pathogen can be accomplished by the use of emm gene-specific oligonucleotide probes. Two technical modifications (a reverse dot blot and a reverse line blot hybridization assay) of a novel approach for the type-specific identification of emm genes have been dev...
Seven strains of Borrelia burgdorferi isolated from ticks and from human beings in Europe and U.S.A. were analyzed for DNA restriction patterns with several enzymes and for DNA homology in Southern blot hybridizations. The restriction patterns showed a moderately high variability. In Southern blot hybridization, strain B31 (U.S.A.) DNA gave a strong signal with itself, strain Bsf (U.S.A.) and A...
Genetically engineered tomato (Lycopersicon esculentum) with the ability to synthesize glycinebetaine was generated by introducing the codA gene encoding choline oxidase from Arthrobacter globiformis. Integration of the codA gene in transgenic tomato plants was verified by PCR analysis and DNA blot hybridization. Transgenic expression of gene was verified by RT-PCR analysis and RNA blot hybridi...
The identification of phylogenetic clusters of bacteria that are common in freshwater has provided a basis for probe design to target important freshwater groups. We present a set of 16S ribosomal RNA gene-based oligonucleotide probes specific for 15 of these freshwater clusters. The probes were applied in reverse line blot hybridization, a simple method that enables the rapid screening of PCR ...
A chemiluminescence dot blot hybridization assay was used for the detection of B19 parvovirus DNA in human sera by using digoxigenin-labeled probes. The probes were revealed immunoenzymatically by use of anti-digoxigenin Fab fragments conjugated with alkaline phosphatase. The chemiluminescence signal was obtained by reacting the labeled probe-target complex with an enzyme-triggerable dioxetane ...
