Staining of cell wall poly P of Volvox aureus and Coleochaete scutata. The confocal microscopic pictures and corresponding scattered light pictures show Volvox aureus and Coleochaete scutata cells (green: poly P staining, red: chlorophyll). Both algae were stained with EcPPXc and EcLonA (left) and the specificity of the poly P staining was controlled by competition with soluble poly P (right).
