Overview
- Product nameHeLa Cell Cycle Lysate Set: Control/Thymidine/Nocodazole
- Species reactivityReacts with: Human
- Product overview
ab136811 contains 3 vials of HeLa whole cell lysates from cells in different stages of the cell cycle: asynchronous, G1/S and G2/M. Asynchronous cells were harvested from untreated, subconfluent plates and this lysate contains cells in all stages of the cell cycle. G1/S cells were harvested following a double thymidine block procedure and represents cells at the G1 to S-phase transition (excess thymidine inhibits DNA synthesis). G2/M cells were harvested following sequential treatments with thymidine and nocodazole and represents cells that have duplicated DNA but are blocked at mitosis (nocodazole inhibits microtubule polymerization).
- Notes
Each whole cell lysate was made by solubilizing cells in an SDS lysis buffer followed by BCA protein quantification and normalization to 1mg/mL in SDS-PAGE sample buffer. A parallel treated sample of cells for each condition was analyzed by propidium iodide staining and flow cytometry to confirm cell cycle stage.

Western blotCdk2 pTyr15 and Histone H3 pSer10 bands are present in asynchronous cells. Cdk2 pTyr15 is elevated in G1/S arrested cells. Conversely, Histone H3 pSer10 is elevated in G2/M arrested cells. Primary antibody: All lanes Cell Cycle WB cocktail (ab136810) diluted to 1X in 4% milk/PBS. Lane 1: HeLa lysate; Untreated, asynchronous cells Lane 2: HeLa lysate; G1/S arrested cells (thymidine treatment) Lane 3: HeLa lysate; G2/M arrested cells (sequential thymidine and nocodazole treatments) All lysates at 15 µg per lane. Lysates are HeLa Cell Cycle Lysates (ab136811). Secondary antibody: All lanes anti-rabbit-HRP. Predicted band size: 42, 33, 17 kDa. -
Cell cycle analysis by flow cytometryA portion of the cells from which the HeLa Cell Cycle Lysates (ab136811) made were analyzed for cell cycle by propidium iodide staining and flow cytometry. Asynchronous (untreated) cells show the classic distribution of 2N, 2N-4N and 4N DNA content representing G1, S and G2/M cell cycle phases. The G1/S arrested cells (treated by double thymidine block) are enriched for the 2N DNA peak. The G2/M cells (treated by sequential thymidine and nocodazole) are enriched for the 4N peak. This figure presents quantification of the propidium iodide histograms. -
