    Notes: SYNOPSIS Vitamin B12 deficiency arrests cell division in Euglena gracilis. B12 starvation for short periods made it possible to induce synchronous growth by addition of the vitamin. Culture conditions were established to optimize replenishment synchrony. The DNA content of E. gracilis in steady state culture and vitamin B12 deficiency culture was measured by flow cytofluorometry and was consistent with colorimetric determinations. The cell volume and DNA distributions of E. gracilis in synchronous culture were analyzed and the sequential changes during the division cycle were computed. Synchronous culture permits more definitive studies of shifts in cell volume and DNA distributions, in which the biochemical events required for cell division are presumably synchronized.

    Notes: SYNOPSIS. Cells of Euglena gracilis strain Z were extracted with trichloroacetic acid. Samples of gross cellular protein were hydrolyzed by a variety of reagents. Amino acids released by these procedures were analyzed and the overall composition of cell protein was quantitatively determined.

    Notes: SYNOPSIS The DNA content of Euglena gracilis and murine leukemic cell line L-1210 were varied by growth under abnormal conditions. DNA measurements by colorimetry and by flow microfluorometry were compared and absolute calibration of the flow device was established.
