Product Info
Background During each cell cycle cyclins undergo periodic accumulation and destruction. As key regulators of the cell cycle the cyclins control important transitions by activating Cdks (1,2). Cyclin A regulates at least two cdks, Cdc2 p34 and Cdk2, and is believed to be necessary for progression through S phase and is active during the G2-M transition (1&3,4). Cyclin B1 also associates with Cdc2 p34 and this complex is requisite for the G2-M progression. The Cyclin B1/Cdc2 p34 complex is known as MPF, M-phase kinase, maturation-promoting factor, or M-phase specific histone kinase, is widely accepted as the trigger of mitosis in all organisms (5-9).
