The addition of exogenous substrates can be used to block cells in certain phases of the cell cycle and frequently target cell cycle checkpoints. These techniques can be carried out in vitro and do not require removal from the culture environment. The most common type of chemical blockade is arrest-and-release, which involves treatment of a culture with a chemical block and subsequent release by washing or addition of a neutralizing agent for the block.
