Abstract
In this study, we recombinantly expressed the V protein of the peste des petits ruminants virus (PPRV) and evaluated its diagnostic value for PPRV infection using an indirect ELISA (i-ELISA). The optimal concentration of the coated antigen of V protein was 15 ng/well at a serum dilution of 1:400, and the optimal positive threshold value was 0.233. A cross-reactivity assay showed that the V protein-based i-ELISA was specific to PPRV with consistent reproducibility and showed a specificity of 82.6% and a sensitivity of 100% with a virus neutralization test. Using the recombinant V protein as an antigen in ELISA is useful for seroepidemiological studies of PPRV infections.
期刊介绍：
Biotechnology can be defined as any technique that uses living organisms (or parts of organisms like cells, genes, proteins) to make or modify products, to improve plants, animals or microorganisms for a specific use. Animal Biotechnology publishes research on the identification and manipulation of genes and their products, stressing applications in domesticated animals. The journal publishes full-length articles and short research communications, as well as comprehensive reviews. The journal also provides a forum for regulatory or scientific issues related to cell and molecular biology applied to animal biotechnology.
Submissions on the following topics are particularly welcome:
- Applied microbiology, immunogenetics and antibiotic resistance
- Genome engineering and animal models
- Comparative genomics
- Gene editing and CRISPRs
- Reproductive biotechnologies
- Synthetic biology and design of new genomes
