Highly sensitive and rapid gene mapping using miniaturized blot hybridization: application to prenatal diagnosis.
We have developed a protocol for the preparation and analysis of amniocyte DNA which permits more sensitive and more rapid antenatal detection of sickle-cell anemia (SCA) than previously has been possible. After rapid extraction of DNA from amniotic cells, only 50 ng of MstII-digested DNA need be analyzed by mini-gel electrophoresis and hybridization detection to determine reliably the fetal ge...
متن کاملDesign and optimization of Dot-blot ELISA system using specific antigens for simple and rapid diagnosis of glanders
Introduction Glanders is one of the oldest contagious and dangerous zoonotic diseases manifesting ulcerative granulomatous lesions on the skin and mucous membranes. Early methods possessing desirable sensitivity and specificity is important to diagnose the disease considering the just only one case report and preventing disease by identification and eradication. The present study was aimed to ...
متن کاملMiniaturized fluorescent RNA dot blot method for rapid quantitation of gene expression
BACKGROUND RNA dot blot hybridization is a commonly used technique for gene expression assays. However, membrane based RNA dot/slot blot hybridization is time consuming, requires large amounts of RNA, and is less suited for parallel assays of more than one gene at a time. Here, we describe a glass-slide based miniaturized RNA dot blot (RNA array) procedure for rapid and parallel gene expression...
متن کاملHighly sensitive northern hybridization using a rapid protocol for downward alkaline blotting of RNA.
A simple and fast RNA gel blot procedure is described that uses 50 mM NaOH to simultaneously transfer and fix RNA to a positively charged nylon membrane. The RNA is transferred in a downward direction, and transfer is routinely completed within 2.5 h. The resulting blots give increased sensitivity over existing methods without affecting RNA integrity and can be used in both radioactive and nonr...
متن کاملRapid screening for freshwater bacterial groups by using reverse line blot hybridization.
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 ...
