Most strains of Staphylococcus aureus express IgG-binding activity and this binding has been considered to be solely mediated by protein A. However, the existence of a second gene in S. aureus strain 8325-4 encoding an IgG-binding polypeptide was recently reported. This novel IgG-binding polypeptide was found after panning a shotgun phage display library,(More)
Streptococcus dysgalactiae is one of the most important bacterial species isolated from bovine mastitis. To identify potential virulence factors of this species we prepared chromosomal DNA from strain 8215 and constructed a phage display library. By affinity selection of the library against fibrinogen (Fg), we isolated and characterized a gene, called demA,(More)
Protein MIG, from Streptococcus dysgalactiae, binds alpha2-macroglobulin and immunoglobulin G (IgG). MIG-derived fusion proteins with one to five IgG-binding repeats differed up to 72,000- fold in avidity for goat IgG, indicating a considerable cooperativity of the repeats. Significant sequence variation in the IgG-binding repeats was recognized. Protein(More)
Streptococcus dysgalactiae, a Lancefield group C streptococcus, is commonly isolated from bovine mastitis. We recently identified a putative regulon in two S. dysgalactiae strains, 8215 and Epi9, consisting of two consecutive genes, dmg and dem, coding for a possible regulatory protein and an M-like protein with fibrinogen- and IgG-binding-properties,(More)
In this paper, for the first time, we analyze non-quasi-static (NQS) effects during single-event upsets (SEUs) in deep-submicron (DSM) MOS devices, using extensive 2D device, BSIM4 and look-up table (LUT) simulations. We know that even for DSM transistors and circuits, the quasi-static approximation is valid for most digital applications. However, a(More)
• Ultra-Wideband Pulse-Radio Transmitter: In this work we utilized high-speed DACs to generate broadband pulses for Pulse-Radio UWB transceivers. We developed ways to reduce sampling images with the help of interleaving and a new Partial-Order Hold DAC architecture. By storing the pulse shapes digitally in an on-chip memory, we can generate fast,(More)
