Notes

The Cell Cycle western blot cocktail (ab136810) is designed to provide a rapid assessment of cell cycle distribution based on molecular markers for the G1/S and M phases of the cell cycle. This is a mixture of three specific rabbit monoclonal primary antibodies targeting phospho-cdk2 Tyr15, phospho Histone H3 Ser10 and beta-actin. Cyclin-dependent kinase 2 (Cdk2) is maintained in an inactive state in G1/S by inhibitory phosphorylation on Tyr15. Histone H3 is phosphorylated at Ser10 when chromosomes condense during mitosis. Hence, elevated phospho-cdk2 Tyr15 indicates G1/S arrested cells and elevated phospho Histone H3 Ser10 indicates M-phase arrested cells when compared to asynchronous cycling control cells. An anti- Actin antibody is included as a loading control. These three readouts are easily resolved by western blot given their different molecular weights.

The recommended dilution for this cocktail is 1:250.

    Western blot – ab136810 Cell Cycle Western Blot Cocktail

    Cdk2 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 250X Cell Cycle WB Cocktail 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 ab136811 HeLa Cell Cycle Lysates

    Secondary antibody: All lanes anti-rabbit-HRP.

    Predicted band size: 42, 33, 17 kDa.

    Hydroxyurea, Camptothecin and Etoposide treatments cause a G1/S-like arrest as judged by the increase in Cdk2 pTyr15 and decrease in Histone H3 pSer10 bands relative to control. In contrast, Paclitaxel causes a G2/M like arrest judged by the decreased Cdk2 pTyr15 and increased Histone H3 pSer10 bands.

    Primary antibody: All lanes Cell 250X Cell Cycle WB Cocktail diluted to 1X in 4% milk/PBS.

    Lane 1: HeLa lysate; Control treatment
    Lane 2: HeLa lysate; 5 mM Hydroxyurea, 24 h treatment
    Lane 3: HeLa lysate; 5 µM Camptothecin, 24 h treatment
    Lane 4: HeLa lysate; 1.5 µM Etoposide, 24 h treatment
    Lane 5: HeLa lysate; 2000 nM Paclitaxel, 24 h treatment

    All lysates at 15 µg per lane.

    Secondary antibody: All lanes anti-rabbit-HRP.

    Predicted band size: 42, 33, 17 kDa.

    Cdk2 pTyr15 intensity decreases and Histone H3 pSer10 intensity increases as a function of Paclitaxel concentration. Equivalent protein loading is indicated by the equal actin intensity across samples.

    Primary antibody: All lanes Cell 250X Cell Cycle WB Cocktail diluted to 1X in 4% milk/PBS.

    Lane 1: HeLa lysate; Control treatment
    Lane 2: HeLa lysate; 0.25 nM Paclitaxel, 24 h treatment
    Lane 3: HeLa lysate; 5 nM Paclitaxel, 24 h treatment
    Lane 4: HeLa lysate; 100 nM Paclitaxel, 24 h treatment
    Lane 5: HeLa lysate; 2000 nM Paclitaxel, 24 h treatment

    All lysates at 15 µg per lane.

    Secondary antibody: All lanes anti-rabbit-HRP.

    Predicted band size: 42, 33, 17 kDa.
