Selection of a DNA aptamer against norovirus capsid protein VP1

Hydroxyproline in the major capsid protein VP1 of polyomavirus.

Amino acid analysis of [3H]proline-labeled polyomavirus major capsid protein VP1 by two-dimensional paper chromatography of the acid-hydrolyzed protein revealed the presence of 3H-labeled hydroxyproline. Addition of the proline analog L-azetidine-2-carboxylic acid to infected mouse kidney cell cultures prevented or greatly reduced hydroxylation of proline in VP1. Immunofluorescence analysis per...

Different Antibody Response against the Coxsackievirus A16 VP1 Capsid Protein: Specific or Non-Specific

Coxsackievirus A16 (CA16) is one of the major causative agents of hand, foot, and mouth disease worldwide. The non-neutralizing antibody response that targets CA16 VP1 remains poorly elucidated. In the present study, antibody responses against CA16 VP1 in Shanghai blood donors and Shanxi individuals were analyzed by ELISA and inhibitory ELISA using five CA16 VP1 antigens: VP11-297, VP141-297, V...

selection of high affinity dna-aptamer for activated protein c using capillary electrophoresis

Induction of protective immune responses against EV71 in mice by baculovirus encoding a novel expression cassette for capsid protein VP1.

EV71 is a major causative agent of hand, foot and mouth disease (HFMD) and is responsible for large outbreaks in various Asian Pacific countries. In the present study, we generated the recombinant baculovirus (Bac-VP1) encoding VP1 in a novel expression cassette. The transmembrane domain of hemagglutinin of the H3N2 influenza virus was included in the cassette as a minimal membrane anchor for V...

Development and characterization of a potential diagnostic monoclonal antibody against capsid protein VP1 of the chicken anemia virus

Chicken anemia virus (CAV) is an important viral pathogen that causes anemia and severe immunodeficiency syndrome in chickens worldwide. In this study, a potential diagnostic monoclonal antibody against the CAV VP1 protein was developed which can precisely recognize the CAV antigen for diagnostic and virus recovery purposes. The VP1 gene of CAV encoding the N-terminus-deleted VP1 protein, VP1Nd...
