Magnetic-sensitive dextran-ferrite microspheriods (MSDFM) with a diame
ter of approximately 100 nm were converted to dextran polyaldehyde-fer
rite and used for immobilizing immunoglobulins and anti-streptokinase
antibodies. Covalent binding of immunoglobulin on MSDFM yields an immu
nosorbent as confirmed by immunoenzyme assay.
