Requiring only simple heating devices, isothermal nucleic acid-based amplification (NASBA) is a potential detection platform to be developed for on-site diagnosis of aquaculture pathogens. In this report, an NASBA assay has been developed for the Taura syndrome virus (TSV), one of the most devastating RNA virus pathogens for several penaeid shrimp species. The NASBA amplicons were detected by a...

background and objective: an outer membrane protein (omp) of helicobacter pylori namely oipa, is an important vir- ulence factor associated with peptic ulcer and gastric cancer risks. the purpose of this study was to isolate the 34 kda omp of h. pylori and evaluate its immunogenicity in experimental animals for rapid detection of more virulent h. pylori isolates. material and methods: sarcosine...

BACKGROUND A variety of approaches to understanding protein structure and function require production of recombinant protein. Mammalian based expression systems have advantages over bacterial systems for certain classes of protein but can be slower and more laborious. Thus the availability of a simple system for production and rapid screening of constructs or conditions for mammalian expression...
