Elevated levels of neutrophil elastase in CPOD (Chronic Obstructive Pulmonary Disease) airways are regarded as the main trigger lung destruction and inflammation. SLPI (Secretory leukocyte protease inhibitor), an inhibitor protease, represents attractive candidate for treatment chronic diseases due to proteases excess. The antiprotease active site has been located on C-terminal domain. This stu...

background: echinococcosis is a zoonotic parasitic disease of humans and various herbivorous domestic animals transmitted by the contact with domestic and wild carnivores,mainly dogs and foxes. the aim of this study is the production, purification and evaluation immunogenicity of new construction of eg95 protein. methods: the recombinant plasmid pet32-a+ used for eg95 expression was constructed...

conclusions the rabies virus np could be extracted and purified in an appropriate amount from infected cell culture. the results of sds-page analysis showed that the intact rabies virus np had been purified properly and thus could be used for further steps to produce the specific diagnostic rabies conjugate. results the volume of the lysate was 15 ml and it became 2.5 ml after purification, wit...

The aim of this study is to identify, clone and express a Mycobacterium avium subsp. paratuberculosis specific immunogenic antigen candidate, in order to develop better reagents for diagnosis and vaccines for the protection of the host. Therefore, MAP2191 gene (a member of MAPmce5 operon) from MAP, was isolated and characterized by Bioinformatics tools and <e...

The silver crucian carp (Carassius auratus gibelio), a gynogenetic teleost, is a promising model for the study of evolutionary genetics in vertebrates. We identified ten gynogenetic clones (FZ-I~FZ-X) from triploid silver crucian carp, collected from Fangzheng County in Heilongjiang Province, China, using microsatellite markers. The genetic diversity of these gynogenetic clones was analyzed usi...
