Abstract:
The invention is directed to the preparation of magnetic and non-magnetic particles coated with a polyaldehyde dextran material and a process for making the same. The polyaldehyde dextran coated particles of the invention are suitable for use in immunological assays and exhibit a reduced matrix effect in such assays when compared to convention particles without a polyaldehyde dextran coating.
