title: Cell cycle analysis and synchronization of the TN-368 insect cell line.
abstract: A cell cycle analysis of the Trichoplusia ni (TN-368) insect cell line is described. By means of autoradiography and percent labeled metaphase data, the cell cycle parameters were determined to be as follows: S, 4.5 hr; G2, 8.5 hr; M, 0.5 hr; G1, 1.0 hr; the total cell time being 14.5 hr. A synchronization procedure using 50 mM thymidine in a double block procedure was used to provide a method of obtaining a large number of cells in particular cell cycle phases, especially S and G2.
