Western Blot: 1 μg/mL for HRPO/ECL detection. Recommended blocking buffer: BSA/Tween 20 based blocking buffer. DO NOT USE MILKOR CASEIN FOR BLOCKING! ELISA: 0.05 μg/mL. Immunoprecipitation: 1-10 μg per 10^6 pervanadate-treated A431 cells. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Protocol
Positive control: pSer / pThr Molecular Weight MarkerFormulation: The pSer/pThr molecular weight marker contains rabbit muscle phosphoproteins isolatedby Fe3+/IDA - affinity chromatography. Proteins are lyophilized fromPBS/NaF/PEG/Sucrose/ Bromophenolblue and Na - azide. After reconstitution the solutioncontains 0. 09% Na-azide. Stability: Reconstitute by addition of 200 µl H2O. After complete solubilization add 200 µl 2xSDS-PAGE sample buffer, mix and incubate at 90°C for 5 min. Application: The pSer/pThr molecular weight marker is recommended for immunoblot applications. Use20µl molecular weight marker per lane. Note: Use BSA based blot incubation buffers. Milk,Casein and Blotto might interfere with antibody - antigen interaction. Storage: Aliquote and store frozen. Avoid repeated freeze/thaw cycles. Shelf life: one year from despatch.
This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

Storage Comment
Store lyophilized (preferably in a desiccator) at -20 °C and reconstituted (aliquote andfreeze in liquid nitrogen) at -80 °C. Avoid repeated freezing and thawing. Thaw aliquots at 37 °C. Thawed aliquots may be stored at 4 °C up to 1 week. 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. Please note that phosphoserine detection by monoclonal antibodies is always dependent on the surrounding amino acid sequence!
