摘要: In a method for the synthesis of a colloid including a superparamagnetic metal oxide coated with a polymer, an acidic solution of a metal salt and a polymer may be cooled, and then neutralized by the controlled addition of a cool solution of a base, and may then be converted, by the application of heat, to a homogenous superparamagnetic metal oxide colloid. According to a preferred embodiment, the polymer may be a polysaccharide. In a further embodiment of the invention, the polysaccharide may be dextran and the metal salt may be ferrous and ferric salts, which produces, according to the methods of the invention, a superparamagnetic iron oxide colloid with an extended plasma half-life.

摘要: Prostatic acid phosphatase is immunologically unstable under typical laboratory conditions. Thus it is necessary to combine a stabilizing composition with samples taken for immunological assay of prostatic acid phosphatase content, and to similarly stabilize prostatic acid phosphatase-containing reagents in kits used to assay the enzyme.
