Detection of pinocytic activity using selective staining with phosphotungstic acid

Summary

Post-staining with phosphotungstic acid has been investigated using thin sections of isolated tomato fruit protoplast material. Certain areas of the plasmalemma and some cytoplasmic vesicles were found to stain intensely, and this selectivity of staining has been shown to be associated with pinocytic activity.
