    Notes: [Auszug] Small disks (5 mm. diam., l mm. thick) were cut from the interior of a freshly dug iris root which had just finished blossoming. The disks (0-3 gm.) were incubated in air, at 28 C., in 1-0 ml. 0-03 M phosphate buffer, pK 5-0, which contained 5 x 10~3 (moles of 3H-thymine (2 -4 x 107 c.p.m. counted ...

    The fine structure of the pellicle ofEuglena gracilis as revealed by freeze-etching (1970)

    Notes: Summary The ultrastructure of the pellicle ofEuglena gracilis (Klebs) “Z” strain was studied using the freeze-etching technique and the results were correlated with data obtained from thin sections of fixed material. Examination of freeze-etched pellicles reveals an outer particulate layer and an inner striated layer. The particles of the outer layer measure approximately 150 Å in diameter. The striations of the inner layer are about 50 Å wide and are separated from each other by about 35 Å. A broad repeating pattern is also visible with a periodicity of about 450 Å. When deep etching is employed, a smooth outer layer is seen covering the particulate layer. This is probably the outer surface of the plasma membrane. Mucilage is present on the outer surface of the cell and is seen as a substructure of threads superposed on the smooth layer of plasma membrane. Thin sectioning also shows a striated layer interior to the plasma membrane. This appears to be identical to the striated layer seen after freeze-etching.
