Differential expression of cyclins A, B1, D3 and E in G1 phase of the cell cycle between the synchronized and asynchronously growing MOLT-4 cells.

The use of 'double-thymidine block' was the first widely accepted method for inducing cell synchrony and remains one of the most effective and frequently used techniques for analyzing the cell cycle today. While thymidine is in itself an inhibitor of DNA replication, thymidine blocks are typically used to generate cell synchrony at the G1/S boundary. We have previously presented the first evidence that shows the growth imbalance and altered...
