Fig. 1From: Development of monoclonal antibodies and serological assays specific for Barley yellow dwarf virus GAV strainElectron micrograph of purified Barley yellow dwarf virus (BYDV) GAV particles. Virus particles were purified from the BYDV GAV-infected wheat plant tissues through differential centrifugation. Purified virus samples were loaded on formvar-coated grids, negatively stained with 2 % (w/v, g · mL−1) phosphotungstic acid and examined under an electron microscope. Bar = 50 nmBack to article page
