Immunofluorescent analysis of Cyclin A (green) in HeLa cells left untreated (UT, left panels) or treated with 100nM camptothecin (CPT, right panels). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS and blocked with 1% Blocker BSA (Product # 37525) for 15 minutes at room temperature. Cells were probed with a Cyclin A monoclonal antibody (Product # MA1-154) at a dilution of 1:50 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502). Nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249; lower panels) for 30 minutes. Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification. Note: Red arrows indicate nuclear translocation of Cyclin A in response to treatment.

MA1-154 detects Cyclin A in mammalian samples and has been successfully used in Immunohistochemistry (Frozen and Paraffin), Immunofluorescence, Immunoprecipitation and Western Blot procedures. Immunoprecipitation and Western Blot analysis with MA1-154 show the accumulation of a prominent band at ~50 kDa in camptothecin and hydroxyurea treated cells. In Immunofluorescence applications, MA1-154 shows nuclear translocation of Cyclin A in G2/M arrested cells as a result of camptothecin treatment.
The protein encoded by the CCNA2 gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. In contrast to cyclin A1, which is present only in germ cells, cyclin A2 is expressed in all tissues tested. Cyclin A binds and activates CDC2 or CDK2 kinases, and thus promotes both cell cycle G1/S and G2/M transitions.

APOLLON protein promotes early mitotic CYCLIN A degradation independent of the spindle assembly checkpoint.
MA1-154 was used in western blot to study the spindle assembly checkpoint-independent regulation of mitotic cyclin A by the APOLLON protein
