Antibody-based proteomics provides a powerful approach for the functional study of the human proteome involving the systematic generation of protein-specific affinity reagents. We used this strategy to construct a comprehensive, antibody-based protein atlas for expression and localization profiles in 48 normal human tissues and 20 different cancers. Here we(More)
An attractive path forward in proteomics is to experimentally annotate the human protein complement of the genome in a genecentric manner. Using antibodies, it might be possible to design protein-specific probes for a representative protein from every protein-coding gene and to subsequently use the antibodies for systematical analysis of cellular(More)
Here we describe the first reported use of a Gram-positive bacterial system for the selection of affinity proteins from large combinatorial libraries displayed on the surface of Staphylococcus carnosus. An affibody library of 3 x 10(9) variants, based on a 58 residue domain from staphylococcal protein A, was pre-enriched for binding to human tumor necrosis(More)
Novel surface proteins can be introduced onto bacterial cell surfaces by recombinant means. Here, we describe various applications of two such display systems for the food-grade bacteria Staphylococcus carnosus and Staphylococcus xylosus, respectively. The achievements in the use of such staphylococci as live bacterial vaccine delivery vehicles will be(More)
A great need exists for the systematic generation of specific antibodies to explore the human proteome. Here, we show that antibodies specific to human proteins can be generated in a high-throughput manner involving stringent affinity purification using recombinant protein epitope signature tags (PrESTs) as immunogens and affinity-ligands. The specificity(More)
Monospecific antibodies dfdfdfdf (msAbs) generated through antigen specific purification of polyclonal antisera are valuable tools in proteome analyses. However, proteome wide generation of msAbs would require extensive immunization programs. Therefore, it would be desirable to develop efficient immunization and purification methods to reduce the number of(More)
Defining the protein profiles of tissues and organs is critical to understanding the unique characteristics of the various cell types in the human body. In this study, we report on an anatomically comprehensive analysis of 4842 protein profiles in 48 human tissues and 45 human cell lines. A detailed analysis of over 2 million manually annotated,(More)
Display of heterologous proteins on the surface of micro-organisms, enabled by means of recombinant DNA technology, has become an increasingly popular strategy in microbiology, biotechnology and vaccinology. Both Gram-negative and Gram-positive bacteria have been investigated for potential applications. The present review will describe the most commonly(More)
We have investigated a staphylococcal surface display system for its potential future use as a protein library display system in combinatorial biochemistry. Efficient affinity-based selections require a system capable of fine affinity discrimination of closely related binders to minimize the loss of potentially improved variants. In this study, a(More)
