Here we show that an affinity proteomics strategy using affinity-purified antibodies raised against recombinant human protein fragments can be used for chromosome-wide protein profiling. The approach is based on affinity reagents raised toward bioinformatics-designed protein epitope signature tags corresponding to unique regions of individual gene loci.

- Affinity proteomics. Affinity proteomics represented by antibody-based arrays is a novel technology with great promise for high-throughput proteomics in health and disease.

(2014) introduced a high-performance affinity enrichment approach for mass spectrometry (AE-MS)- based evaluation of protein-protein interactions. 1 The research team contrasted the new methodology with traditional affinity purification (AP-MS), finding that it gave comparable results from a simpler workflow. Sacco et al. found that the affinity proteomics data identified a number of protein interactors that co-enriched with the phosphatase enzymes under examination, with around 10% of the data reported elsewhere in research literature. Their new affinity proteomics approach also identified new phosphatase interactions such as DLC1 and ATM. Various methods are used to enrich or purify a protein of interest from other proteins and components in a crude cell lysate or other sample. The most powerful of these methods is affinity chromatography, also called affinity purification, whereby the protein of interest is purified by virtue of its specific binding properties to an immobilized ligand. An Isotope-coded affinity tag (ICAT) is an in-vitro isotopic labeling method used for quantitative proteomics by mass spectrometry that uses chemical labeling reagents.

affinity chromatography, or SMOAC (Figure 1B), in which phosphopeptides are first enriched by TiO 2 resin followed by enrichment with Fe-NTA resin.

In recent years, advances in binder technologies have created the potential for an unprecedented view on protein expression and distribution patterns in plasma, cells and tissues and increasingly on protein function. APOSTL is an interactive affinity proteomics analysis software developed to reformat affinity proteomics data (both spectral counting and MS1) for input into the SAINTexpress statistical package and to visualize the output(s). - bornea/APOSTL We use cookies to enhance the usability of our website.

Within Affinity Proteomics Group we develop, design and apply recombinant antibody microarrays for high-throughput (disease) proteomics, with a particular focus on oncoproteomics and autoimmunity. We have adopted a cross-disciplinary technological approach to develop a state-of-the-art recombinant antibody microarray technology platform capable of handling most sample formats.

Affinity depletion is based on the specific capture of target proteins using immobilized antibodies or other molecules (protein A/G, Cibacron Blue) with high affinity and specificity for the targets. Simultaneous removal of multiple high abundant proteins has become the major pre-analytical strategy for proteomic analysis of blood plasma [ 9 ].
