Abstract
Recombinant proteins, commonly expressed in fusion with an affinity tag to facilitate purification, are often used as immunogens for polyclonal antibody production. Careful immunopurification of the antibody product is often the key to obtaining a high-specificity polyclonal antibody against the protein domain of interest. This study describes the purification and characterization of such an antibody directed against the adenomatous polyposis coli (APC) tumour suppressor. We used a combination of affinity chromatography and biosensor analysis to optimize and monitor antibody purification. This antibody was then characterized by immunoprecipitation, proteomic analyses and immunofluorescence staining and shown to be a valuable reagent for the study of APC biology. Using this antibody we successfully isolated and identified APC, using MS/MS, from transfected cell lines. A novel phosphorylation site on APC was identified at ser 1436. Similar strategies involving multiple immuno-affinity steps coupled with surface plasmon resonance (SPR), immunoprecipitation proteomic and immunofluorescence analyses should be generally applicable for the purification and characterization of other polyclonal antibodies.

Abstract
A biosensor-based micro-affinity purification method to recover protein binding partners and their complexes for down stream proteomics analysis has been developed using the BIAcore 3000 fitted with a prototype Surface Prep Unit (SPU). The recombinant GST-intracellular domain of E-cadherin or the recombinant GST-beta-catenin binding domain of Adenomatous Polyposis Coli (APC) were immobilized onto the SPU and used to affinity purify binding partners from chromatographically enriched SW480 colon cancer cell lysates. A GST- immobilized surface was used as a control. Samples recovered from the SPU were subjected to SDS-PAGE with sensitive Coomassie staining followed by automated in-gel digestion and LC-MS/MS. The results obtained using the SPU were compared with similar experiments performed using Sepharose beads.
