Selection and Antigenic Characterization of Immune-Escape Mutants of H7N2 Low Pathogenic Avian Influenza Virus Using Homologous Polyclonal Sera

Understanding the dynamics of the choice of influenza A immune escape variants by serum antibody is crucial for designing efficient vaccination packages for animals, particularly poultry the place massive populations have a brief era time and could also be vaccinated with excessive frequency. In this report, immune-escape mutants of A/turkey/New York/4450/1994 H7N2 low pathogenic avian influenza virus,

An ultrasensitive impedance biosensor for Salmonella detection based on rotating high gradient magnetic separation and cascade reaction signal amplification

An impedance biosensor utilizing rotary magnetic separation and cascade reaction was developed for fast and ultrasensitive detection of Salmonella typhimurium. First, magnetic nanoparticles (MNPs) modified with anti-Salmonella monoclonal antibodies have been injected right into a capillary on the presence of a rotary high gradient magnetic area, which was rotated by a stepper motor. Then, a bacterial pattern
