The tubulin-binding protein gephyrin, which anchors the inhibitory glycine receptor (GlyR) at postsynaptic sites, decorates GABAergic postsynaptic membranes in various brain regions, and postsynaptic gephyrin clusters are absent from cortical cultures of mice deficient for the GABA(A) receptor gamma2 subunit. Here, we investigated the postsynaptic(More)
The detection of cell-bound proteins that are produced due to aberrant gene expression in malignant tumors can provide important diagnostic information influencing patient management. The use of small radiolabeled targeting proteins would enable high-contrast radionuclide imaging of cancers expressing such antigens if adequate binding affinity and(More)
Small protein domains, capable of specific binding to different target proteins have been selected using combinatorial approaches. These binding proteins, called affibodies, were designed by randomization of 13 solvent-accessible surface residues of a stable alpha-helical bacterial receptor domain Z, derived from staphylococcal protein A. Repertoires of(More)
Affibody (affibody) ligands that are specific for the extracellular domain of human epidermal growth factor receptor 2 (HER2/neu) have been selected by phage display technology from a combinatorial protein library based on the 58 amino acid residue staphylococcal protein A-derived Z domain. The predominant variants from the phage selection were produced in(More)
We investigate the relation between the multichromatic number (discussed by Stahl and by Hilton, Rado and Scott) and the star chromatic number (introduced by Vince) of a graph. Denoting these by χ∗ and η∗, the work of the above authors shows that χ∗(G) = η∗(G) if G is bipartite, an odd cycle or a complete graph. We show that χ∗(G) ≤ η∗(G) for any finite(More)
Approaches to direct solid phase sequencing of genomic and plasmid DNA have been developed using magnetic beads, coated with streptavidin, as solid support. The DNA is immobilized through selective incorporation of biotin into one of the strands. A single stranded template, suitable for sequencing, is obtained through strand-specific elution. Using this(More)
Genetic engineering enables the construction of gene man Genome Project (5), efficient and robust production and purification strategies are necessary (6). For fusions resulting in fusion proteins having the combined properties of the original gene products. Fusion industrial production of recombinant proteins, simple and fast purification methods(More)
The genetic diversity displayed by Plasmodiumfalciparum field isolates, the occurrence of variant forms of the parasite at different frequencies in different geographic areas, and the complexity of the infections represent major obstacles for the development of effective malaria control measures. However, since most of the existing studies have been(More)
Recent reports have demonstrated beneficial effects of proinsulin C-peptide in the diabetic state, including improvements of kidney and nerve function. To examine the background to these effects, C-peptide binding to cell membranes has been studied by using fluorescence correlation spectroscopy. Measurements of ligand-membrane interactions at(More)
Display of heterologous proteins on the surface of microorganisms, enabled by means of recombinant DNA technology, has become an increasingly used strategy in various applications in microbiology, biotechnology and vaccinology. Gram-negative, Gram-positive bacteria, viruses and phages are all being investigated in such applications. This review will focus(More)
