Extraction model of the longitudinal flagellum of Ceratium tripos (dinoflagellida): Reactivation of flagellar retraction [PDF]

Journal of Cell Science, 1985
ABSTRACT The mechanism of retraction of the longitudinal flagellum of Ceratium tripos was studied by making extracted models of the flagellum. Non-detergent models extracted in low ionic strength medium containing 1 M-glucose, 10mM-EDTA and 50mM-Tris.
