    Notes: [Auszug] CERTAIN chemicals have come to stand for particular areas of biological research. Think of fluorescein isothiocyanate; 2-deoxyglucose; bis-acrylamide; a-bung-arotoxin, anti-mouse immunoglobulin. Substances such as these are hitched so firmly to a line of research that you could almost use their ...

    Notes: [Auszug] CADMIUM is a ubiquitous metal, having widespread and increasing uses in various products including nickel-cadmium batteries, solar cells and electroplating. The element is not essential to man, being virtually absent at birth but gradually increasing with age by absorption from the diet, from ...

    Notes: [Auszug] FOR over a century investigators have been fascinated by the mechanisms by which blood remains in a fluid state while circulating in vivo but forms a fibrin-platelet thrombus in vitro or in disease states. Current research directed at solving this problem was presented at the Vllth International ...
