HCVpp system (also called as HCV pseudoparticle) generates virus particles, which display E1-E2 glycoproteins of HCV on their surface.
Serum specimens with sufficient volume were tested using 4 CDC serologic assays: 1) microneutralization (MN) assay (37); 2) spike (S)-specific pseudoparticle neutralization assay (VSV-MERS-S); 3) S ELISA (Ig-specific) (38); and 4) nucleocapsid (N) ELISA (Ig-specific) (37,38).
Then we give a second set of Bogoliubov transformations that map the untangled oscillators into two different representations: the time-independent and the time-dependent pseudoparticle representations, respectively, which are needed to define the vacuum in which the physical quantities should be computed and to determine the dynamics of the thermal oscillators.
A stack of platelets including organomodifler or polymer chains between clay layers can be considered as a pseudoparticle, which has a lower effective aspect ratio and higher volume fraction.
We screened serum samples by using a MERS-CoV ELISA (7) and confirmed the results by using a MERS-CoV pseudoparticle neutralization test (8).
