ELISA: Use at 0.05 μg/mL. Immunoprecipitation: Use at 1-10 μg per 10^6 pervanadate-treated A431 cells. Western Blot (Immunoblotting): 1 μg/mL for HRPO/ECL detection. Recommended blocking buffer: BSA/Tween 20 based blocking buffer. DO NOT USE MILKOR CASEIN FOR BLOCKING! Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
实验流程
Positive Control: pSer / pThr Molecular Weight MarkerFormulationThe pSer/pThr molecular weight marker contains rabbit muscle phosphoproteins isolatedby Fe+/IDA-affinity chromatography. Proteins are lyophilized fromPBS/NaF/PEG/SUCROSE/Bromophenolblue and Na-azide. After reconstitution the solutioncontains 0. 09% Na-azide. StabilityReconstitute by addition of 200 µl H2O. After complete solubilization add 200 µl 2xSDS-PAGE sample buffer, mix and incubate at 90°C. ApplicationThe pSer/pThr molecular weight marker is recommendede for immunoblot applications. Use 20 µl molecular meight marker per lane. Note: Use BSA based blot incubation buffers. Milk, Casein and Blotto might interfere withantibody - antigeninteraction. StorageAliquote and store frozen. Avoid repeated freezing and thawing. Shelf life: one year from despatch.

Phosphorylation and dephosphorylation of cellular proteins are central steps in transducing extracellular signals to the cell nucleus. Phosphorylated epitopes may serve as docking sites for the assembly of protein complexes or may alter the 3-dimensional protein structure thus modulating enzymatic activity or the ability to undergo protein-protein-interactions. Modification of proteins on serine residues is mediated by serine/threonine kinases.
