Double-thymidine block
WebOverreplication at early and late origin regions during S phase. (A) HeLa cells arrested in early S phase by a double-thymidine block (0-h sample) were released in thymidine-free medium, and their progress through S phase was monitored by FACS analysis. The profile of an exponential asynchronous culture is also shown (Exp). WebMedical Definition of Double thymidine block. 1. A lab technique used to synchronise the cell cycles of all the cells in a culture. This is done by adding excessive amounts of …

For G1 phase synchronization, approximately 75%–80% cells are in G1/S border using thymidine double block method. 4. For S phase synchronization, typically, approximately 73%–76% of the cells will be in S phase, 14%–16% in G1 phase, and 10% ...
WebSep 9, 2024 · National Center for Biotechnology Information WebCells were arrested at the beginning of S phase using a double thymidine block and cell synchrony monitored by flow cytometry of propidium iodide stained cells. Flow cytometry data were collected for each of the three independent double thymidine blocks performed in this study; data are shown only for the second double thymidine arrest (Thy ...
WebSep 5, 2024 · The protocol to synchronize cells at G1/S boundary by using double thymidine block is presented, which could help to obtain cells at distinct cell cycle stage through synchronization. Cell synchronization is widely used in studying mechanisms involves in regulation of cell cycle progression. Through synchronization, cells at distinct …
WebAdherent HeLa cells were synchronized using a double thymidine block method. Thymidine (Sigma) was added to the cell culture media at a final concentration of 2 mM from a 100 mM stock solution in water.
