特异性ab12281 is specific for the phosphorylated form of the Cdc27 (phospho T244). Less than 1% reactivity is observed against the non-phosphorylated form of the immunizing peptide. The antibody does not cross-react with Cdc27 phosphorylated at other sites.
纯化说明The product was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
应用说明ELISA: 1/3000 - 1/15000. Reactivity with non-phosphorylated human Cdc27 is minimal by ELISA.
IF: Use at an assay dependent dilution.
WB: 1/300 - 1/2000. Detects a band of approximately 92 kDa.
ICC/IF: Use at an assay dependent dilution (from PubMed: 17472438).
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
功能Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins: it mainly mediates the formation of 'Lys-11'-linked polyubiquitin chains and, to a lower extent, the formation of 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains.
通路Protein modification; protein ubiquitination.
序列相似性Belongs to the APC3/CDC27 family. Contains 9 TPR repeats.
翻译后修饰Phosphorylated. Phosphorylation on Ser-426 and Thr-446 occurs specifically during mitosis.
