Phenoloxidase activity in crayfish haemocyte lysates and extracts of haemocyte membranes were studied using native PAGE and SDS-PAGE gels and staining for cresolase, catecholase and laccase activities. The activation of ...

Lipopolysaccharides (LPS) from Gram-negative bacteria are strong stimulators of white river crayfish, Procambarus zonangulus, haemocytes in vitro. Following haemocyte treatment with LPS and with LPS from rough mutant R5 ...

The prophenoloxidase (proPO) system is considered an important mechanism of innate defence in arthropods. This enzymatic cascade has been studied in crustaceans such as the crayfishes Astacus astacus and Pacifastacus ...

Las pruebas inmunoquímicas constituyen una herramienta de diagnostico muy utilizada a nivel comercial y de investigación. Estas pruebas son específicas, versátiles, se pueden realizar varias pruebas al mismo tiempo y en ...

The Ebola virus (EBOV) VP35 protein antagonizes the early, antiviral interferon (IFN) α/β response. We previously demonstrated that VP35 inhibits virus-induced activation of the IFN β promoter by blocking the phosphorylation ...
