Abstract: Polyglutaraldehyde (PGL) is polymerized in aqueous base or in aqueous highly polar solvent basic media to prepare powders, castable films or coatings for substrates such as amine substituted microbeads. PGL microspheres can be prepared by suspension polymerization in presence of a surfactant or by precipitating PGL from solution containing surfactant. Magnetic PGL microspheres are formed by suspension polymerization in the presence of magnetic particles such as iron oxide. Polyglutaraldehyde can be converted to a fluorescent polymer by reaction with m-aminophenol or other reagent. Proteins can be readily covalently bound to the polyglutaraldehyde.

Abstract: Suspension polymerization of aqueous glutaraldehyde in basic conditions in presence of surfactants such as isobutoxy acrylamide copolymers and/or cross-linking agents yield cross-linked, water insoluble glutaraldehyde polymer microspheres ranging in size from 200 A to 10.mu.. Addition of fluorochromes, e.g., FITC, during polymerization yields microspheres of high fluorescent intensity and addition of a suspension of metal containing particles such as Fe.sub.3 O.sub.4 during polymerization yields magnetic microspheres. Immunopolyglutaraldehyde microspheres can be obtained by interacting the polyglutaraldehyde microspheres with antibodies. The immunomicrospheres were used to label and separate cell subpopulations. The labeling specificity is considerably improved by increasing the amount of isobutoxy polyacrylamide incorporated in the microspheres.
