04452773 is referenced by 348 patents and cites 13 patents.

The invention relates to colloidal sized particles composed of magnetic iron oxide (Fe.sub.3 O.sub.4) coated with a polysaccharide, preferably dextran, or a derivative thereof having pendant functional groups. The particles have a magnetic moment, are electron dense, and are stable and non-aggregating under physiological conditions. They can be covalently bonded to antibodies, enzymes and other biological molecules and used to label and separate cells, cellular membranes and other biological particles and molecules by means of a magnetic field.
