In order to determine the best strategy for detection of aerobactin in members of the family Enterobacteriaceae, we compared the results of three phenotypic assays, including a chemical assay, a cross-feeding bioassay, and an enzyme-linked immunosorbent assay (ELISA), with the results of a dot blot hybridization assay using a specific probe for the aerobactin genes. The sensitivity and specific...

We developed a diagnostic test based on the reverse dot-blot principle, in which five mitochondrial point mutations responsible for Leber hereditary optic neuropathy (LHON) were screened simultaneously. A series of wild-type and mutant oligonucleotides representing each mutation were covalently bound to a single nylon membrane strip. The target sites were amplified in a multiplex PCR and the pr...

Telomeres play a central role in human cancer, cardiovascular aging and possibly longevity. However, present methods to measure telomere length are fraught with shortcomings that limit their use. Here, we describe a novel method to measure the relative telomere DNA content by dot blot analysis. In each dot, the DNA content is measured by a DNA stain (Dx) and the telomeric DNA content is measure...

Introduction: To present the clinical findings of Autoimmune hemolytic anemia (AIHA) Retinopathy and its rapid resolutions following treatment with steroid. 
 Case report: A 14-year-old female patient presented decreased vision in left eye. There was history AIHA. Visual acuity 1/60 LE 6/6 RE. conjunctival pallor, other anterior segment were unremarkable. Fundus examination eye revealed fl...

A monoclonal antibody dot-blot assay was used to evaluate detergent lysates of tonsil tissue from mule deer to detect PrP(CWD), the marker for the cervid transmissible spongiform encephalopathy chronic wasting disease (CWD). Samples of formalin-fixed brain and tonsil tissues from mule deer were examined for PrP(CWD) using immunohistochemistry (IHC) with Mab F99/97.6.1, the gold standard for dia...
