The transport of hydrophobic insect pheromones through the aqueous medium surrounding their receptors is assisted by pheromone-binding proteins (PBPs). The protein from the silkworm moth Bombyx mori, BmorPBP, exhibits a pH-dependent conformational change postulated to trigger the release of the pheromone bombykol to its receptor. At low pH, an alpha-helix(More)
Insect pheromone-binding proteins (PBPs) transport sex pheromones through the aqueous layer surrounding G protein-coupled receptors that initiate signaling events leading to mating. This PBP-receptor system strongly discriminates between ligands with subtle structural differences, but it has proved difficult to distinguish the degree of discrimination of(More)
A mouse monoclonal antibody (mAB lu-5) was prepared using a lung cancer cell line as an antigen. The selected clone produces an IgG with a gamma-1 heavy chain and a kappa-light-chain. Immunohistochemical testing of mAB lu-5 on 117 normal tissue biopsies and 474 tumours revealed reactivity with an intracytoplasmic, formaldehyderesistant antigen present in(More)
It is customary to distinguish “primitive”, “classic” and “compact” (“burned out”) senile plaques in Alzheimer's disease and senile dementia of the Alzheimer type (SDAT). Primitive plaques are characterized by altered neurites without accumulation of amyloid, classic plaques by an amyloid core surrounded by altered neurites and compact plaques by amyloid(More)
UNLABELLED BACKGROUND/MATERIAL AND METHODS: In 59 rat mandibular glands we investigated the distribution of extracellular matrix proteins (EMP) in rat salivary gland tumors. The animals differed in age and pretreatment status (irradiation versus no irradiation). For immunohistochemical analysis we used polyclonal EMP antibodies [anti-laminin (AL),(More)
Light microscopic immunohistochemical investigations were performed on neurofibrillary tangles (NFT) in four histologically confirmed cases of Alzheimer's disease (AD) and in five patients with a progressive supranuclear palsy (PSP). The antibody panel included antisera to the neuronal microtubule-associated protein, tau, and to isolated paired helical(More)
The aim of this work was to compare the performance of the AlphaLISA® amplified luminescent proximity homogeneous assay technology platform and an alternative time-resolved fluorescence resonance energy transfer (TR-FRET) technology assay platform for the detection of five biomarkers. These included biomolecules involved in inflammation (TNFa, IL-1b, IL-6),(More)
Section of formaldehyde-fixed paraffinembedded cortical and hippocampal brain tissue from five cases with senile dementia of Alzheimer type (SDAT) and five cases with Pick's disease (PD) were immunostained with the monoclonal antibodies (mabs) 147, RT 97, BF 10 and 8D8 with and without pretreatment with alkaline phosphatase (AP) or trypsin (Tr). The mabs(More)

Kaposi's sarcoma-associated herpesvirus is an emerging pathogen whose mechanism of replication is poorly understood. PF-8, the presumed processivity factor of Kaposi's sarcoma-associated herpesvirus DNA polymerase, acts in combination with the catalytic subunit, Pol-8, to synthesize viral DNA. We have solved the crystal structure of residues 1 to 304 of(More)
