Enteric cytopathogenic human orphan virus 6-type VP1 protein specific epitope, fusion protein of enteric cytopathogenic human orphan virus 6-type VP1 protein specific epitope and preparation method and use of fusion protein

Abstract

The invention discloses an enteric cytopathogenic human orphan virus 6-type VP1 protein specific epitope, a fusion protein of the enteric cytopathogenic human orphan virus 6-type VP1 protein specific epitope and a preparation method and use of the fusion protein and relates to the field of a gene engineering technology, a vaccine and a diagnostic reagent. The preparation method comprises analyzing an enteric cytopathogenic human orphan virus 6-type surface protein VP1 amino acid sequence by a computer, and screening strong specific epitope-containing protein fragments comprising 75th-101th amino acids, 127th-141th amino acids, 204th-237th amino acids and 257th-289th amino acids, wherein the four protein fragments are connected by 2 glycines and 1 serine so that the epitope fusion protein is formed. A codon in favor with eucaryotes and prokaryotes is used, a brand new gene sequence of the epitope fusion protein is chemically synthesized, through a gene engineering technology, the enteric cytopathogenic human orphan virus 6-type VP1 protein epitope fusion protein is expressed and prepared and is used for development of an enteric cytopathogenic human orphan virus antibody detection reagent and preparation of an enteric cytopathogenic human orphan virus monoclonal antibody and polyclonal antibody.

Description

technical field [0001] The preparation and application of specific antigenic epitope of echovirus type 6 VP1 protein and its fusion protein in the present invention relate to the screening of surface VP1 protein fragments of echovirus type 6 containing strong antigenic epitopes, and the preparation of Fusion protein of echovirus type 6 VP1 protein epitope. Select the codons favored by both eukaryotic and prokaryotic organisms, chemically synthesize the gene sequence of a new VP1 protein antigen epitope fusion protein, and express the fusion protein by genetic engineering technology. The expressed fusion protein can be used for Echo virus vaccines and antibody detection reagents Development, etc., the present invention relates to the fields of genetic engineering technology, vaccines and diagnostic reagents. Background technique [0002] Human enteric cytopathogenic orphan virus (Enteric Cytopathogenic human Orphan Virus, ECHO), referred to as Echo virus, is a type of single...
