Mouse anti Human p34 cdc-2 nuclear protein

p34(Cdc2) kinase is a an essential nuclear protein for mitosis in Human cells. During the prophase/metaphase transition the inactive phosphorylated form of p34(cdc2) is dephosphorylated to make the active form of the protein. This dephosphorylation is performed by the p80(cdc25) dual-specificity phosphatase. The regulatory subunit of p34(cdc2) is cyclin B, a 47-52 kDa protein. The p34(cdc2) protein is the catalytic subunit of the M phase-promoting factor (MPF) which is intracellular factor responsible for entry into M phase. Three mechanisms are responsible for the activitation of MPF at the onset of mitosis: binding of p34(cdc2) to cyclin B, a series of phosphorylation/dephosphorylation events on the two subunits and translocation of the complex to the nucleus or microtubules.

Detects three bands within the 34 kDa region corresponding to p34 and its cleavage products. Can also be used for IHC on paraffin-embedded tissue (10 µg/mL) as well as immunocytochemistry and immunoprecipitation. Optimal concentration should be evaluated by serial dilutions.

This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving Humans or animals.
