Monoclonal antibody (MAb) 1B3 against Haemophilus parasuis (H. parasuis) was generated by fusing SP2/0 murine myeloma cells and spleen cells from BALB/c mice immunized with the whole-bacterial-cell suspension of H. parasuis HS80 (serotype 5). The MAb 1B3 showed strong reactivity with 15 serotype reference strains of H. parasuis using Dot blot and Western blot analysis. Immunoprecipitation and p...

To enable rational multi-epitope vaccine and diagnostic antigen design, it is imperative to delineate complete IgG-epitome of the protein. Here, we describe results of IgG-epitome decoding of three proteins from high-risk (HR-) oncogenic human papillomavirus type 58 (HPV58). To reveal their entire epitomes, employing peptide biosynthetic approach, 30 precise linear B-cell epitopes (BCEs) were m...

A conformational epitope is composed of several discontinuous segments as antigenic determinants which are spatially close to each other in the three dimensional structure. These segments form the antigen which may bind with a specific receptor of the immune system, and play an important role in vaccine designs and immuno-biological experiments. Though there are two major types of epitopes: lin...

OBJECTIVE Increasing evidences have suggested the pathogenic role of anti-neutrophil cytoplasmic antibodies (ANCA) directing myeloperoxidase (MPO) in ANCA-associated vasculitis (AAV). The current study aimed to analyze the association between the linear epitopes of MPO-ANCA and clinicopathological features of patients with AAV. METHODS Six recombinant linear fragments, covering the whole leng...

bovine ephemeral fever (bef) is an acute epidemic disease in cattle and water buffalo, spanning tropical and subtropical zones of asia, australia, and africa. in recent years, bef has been distributed in many provinces of iran and caused economic losses. in this study the sequence encoding the g1 epitope of bovine ephemeral fever virus (befv) g glycoprotein was amplified by pcr, ligated into th...

objective(s):multi-epitopic protein vaccines and direction of vaccine delivery to dendritic cells (dcs) are promising approaches for enhancing immune responses against mutable pathogens. escherichia coli is current host for expression of recombinant proteins, and it is important to optimize expression condition. the aim of this study was the optimization of multi-epitopic hiv-1 tat/pol/gag/env ...

Abstract Background The hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) is a major antigen that can induce protective antibodies in poultry. However, its antigenic epitopes have not been fully elucidated. Therefore, defining the linear HN, especially neutralizing epitopes, will be useful for revealing characterization. Methods In this study, we analyzed B-cell immunodo...
