Abstract
The present invention relates a method of preparing agarose beads, which method results in a population of beads which are of relatively uniform particle size. In an advantageous embodiment, the beads are of a particle size less than 10 μm, and the coefficient of variation C.V. of the population is less than 15%. The beads according to the invention are advantageously used in biological separation methods, such as in the production of chromatographic packing materials; drug carriers; or in any method of biological engineering.
