We have used the polymerase chain reaction (PCR) to analyse 420 normal donor blood samples taken at a city centre donation site. Three sets of human cytomegalovirus (HCMV) primers specific to the HXLF6, immediate early and late antigen gp64 genes, of the alpha, beta and gamma antigen coding regions respectively, were used to allow for the possibility of(More)
The purpose of this study was: (a) to examine the effect of plasma-gas composition on plasma polymer oxygen/carbon (O/C) ratio, functional group composition and stability in water, and then (b) to examine cell attachment to surfaces containing different concentrations of O/C and functional groups. Oxygen-functionalised surfaces were deposited by means of(More)
1. The effect of rabbit anti-(pigeon erythrocyte) antibodies plus human complement on the concentration of intracellular free Ca2+ in sealed pigeon erythrocyte 'ghosts' was investigated with the photoprotein obelin. 2. The addition of human serum, as a source of complement, to 'ghosts' coated with antibody caused a rapid increase in intracellular free Ca2+(More)
OBJECTIVE The bond of a silane-coupling agent to a ceramic surface is expected to be influenced by the composition and chemical state of the ceramic surface. The purpose of this study was to determine the variation in the composition and the chemical states of the surfaces of a range of leucite-reinforced feldspathic (LRF) ceramics using X-ray photoelectron(More)
Five monoclonal antibodies to human C9 were produced. Three of the antibodies had affinities from 1.6 to 3.1 X 10(9) M-1 and 2 were of lower affinity, 0.1 to 0.3 X 10(9) M-1. Four distinct antigenic sites on C9 were detected. The lowest affinity antibody was immobilised on Sepharose 4B and used to isolate C9 from human plasma. A 1200-fold purification was(More)
