Anti-Plx Antibody Profile

Antigen: Polo-like-kinase protein; Detects the mitotic from of plx from xenopus and is thought to bind to a phosphorylated epitope
Relevance: Polo-like kinase is a mitotic regulator conserved from yeasts to humans. Many key cell cycle regulators such as p53, cdc25, and cyclin B are directly targeted by polo-like kinase.
Clone: AZ44
Subclass: IgG1
Applications: ELISA, Western blot
Immunogen: baculo expressed Polo Kinase from Xenopus
Reactivity: Xenopus
Species raised in: Mouse: Balb/c
Fusion partner: Sp2/0 Ag.14
Recommended growth conditions: DMEM 5% FCS
References: -
Notes: Plx is activated by phosphorylation. AZ44 only blots the Xenopus mitotic form of Plx which we assume to be due to this antibody recognizing a phosphorylated epitope. Therefore until I have formally proved that this antibody recognises a phosphorylated epitope it is possible that the antibody recognises some other modification, however the most likely explanation is that it blots a phosphorylated epitope. Positive control: xenopus egg extract.  Use at 1ug/ml

                                                                                         

Legend:Blot of Xenopus egg extracts (Mitotic CSF (1) and interphase (2)) and HeLa (human) cell extract (3). Molecular weight markers 120, 98, 68, 57, 43, 32, 18, 12 kD. Note that the phosphorylated form of Plx from the Xenopus mitotic extract migrates slower than the unphosphorylated form present in the interphase extract.
