Figure 1From: Membrane-elution analysis of content of cyclins A, B1, and E during the unperturbed mammalian cell cycleDiagram of membrane-elution apparatus. The apparatus is inverted at the start of an experiment, with cells collected on the membrane surface by suction. Then the apparatus is inverted, and medium fills the space above the membrane as shown. Cells grow on the membrane surface. Newborn cells are released at division, with one cell entering the eluate and the sister cell remaining bound to the membrane.Back to article page
