Thymidine uptake
WebbThe thymidine incorporation assay, the most common assay, utilizes a strategy wherein a radioactive nucleoside, 3H-thymidine, is incorporated into new strands of chromosomal DNA during mitotic cell division. WebbFirst thymidine block. Add thymidine to the cells to a final concentration of 2 m M and incubate for 8 h. 3. Wash the cells three times with 1 × PBS. 4. Add complete DMEM for 4 h to release the cells from the thymidine block. 5. Second thymidine block. Add thymidine to the cells to a final concentration of 2 m M and incubate for 12 h.
