A magnetic capture-hybridization method was assessed for the isolation of prokaryotic mRNA for the neutral protease of B. cereus from liquid culture. A biotin-labeled specific probe was hybridized to the mRNA transcripts and subsequently captured by streptavidin-coated paramagnetic beads. mRNA was detected by dot-blot hybridization with a ds DIG-labeled DNA-probe. The magnetic capture hybridiza...
The G genotyping of 74 group A rotavirus samples was done by RNA-DNA hybridization (dot-blot) using oligonucleotide probes for the VP7 gene region of the human rotavirus serotypes/genotypes 1, 2, 3 and 4. Thirty-one samples could be genotyped by dot-blot showing the following results: G1 = 16, G4 = 6, G3 = 5, and G2 = 4. The data show circulation of genotypes G1-G4 and the predominance of G1. T...
The problem of eradicating tuberculosis (TB) has become more complicated by the emergence of multidrug resistant TB (MDR-TB). Any rapid laboratory method that can be used to detect drug susceptibility of Mycobacterium tuberculosis (MTB) is urgently needed. In this study, we employed the radioisotope (32P)-based PCR-dot blot hybridization method on sputum samples from patients in Jakarta, Indone...
Background and Aims: Viroids are smallest known plant pathogens and cause several economically significant diseases. Until recently, viroid detection relied mainly on biological tests and indexing. Today various diagnostic techniques such as nucleic acid hybridization, southern blot and reverse transcription coupled with polymerase chain reaction (RT-PCR) are being used for detection and diagno...
Dot and slot blotting are simple techniques for immobilizing bulk unfractionated DNA on a nitrocellulose or nylon membrane. Hybridization analysis can then be carried out to determine the relative abundance of target sequences in the blotted DNA preparations. Dot and slot blots differ only in the geometry of the blot, a series of spots giving a hybridization pattern that is amenable to analysis...
A new nonisotopic detection method based on time-resolved fluorescence for nucleic acid hybridization assays with alkaline phosphatase labels has been developed: enzyme-amplified lanthanide luminescence (EALL). EALL combines the amplification of an enzyme label with the sensitivity and background elimination of time-resolved fluorescence detection of lanthanide ion luminescence. The detection s...
