Abstract
Two electrophoretically distinct classes of virus particles, designated fast (AfV-F) and slow (AfV-S) according to their relative electrophoretic mobilities, were isolated from the mycelium of Aspergillus foetidus, strain imi 41871. They were almost completely separated by dialysis against 0.03m-phosphate buffer, pH 7.6, in which F particles remained in suspension, while S particles precipitated, and were further purified by caesium chloride density gradient centrifugation. Electron microscopy showed that both classes were composed of isometric particles of similar diameter.Keywords
