  • Title: Physiological dissection of various effects of ruthenium red dye on Paramecium cells.
    Author: Kaczanowska J.
    Journal: Experientia; 1979 Aug 15; 35(8):1062-4. PubMed ID: 477876.
    Abstract:
    Polycationic dye ruthenium red, but not alcian blue, if externally applied to Paramecium cells quickly inhibits their phagocytosis. Ruthenium red combined with the cell surface diminishes frequency and duration of ciliary reversals and gradually inactivates the Ca++ gating mechanism. This effect persists for 1-3 after ruthenium red removal from the culture medium.
