Abstract:
1. An agarose bead comprising islets, wherein the agarose of said bead has a sulfate content of less than 0.2 wt % but greater than zero, a pyruvate content of 0-0.1 wt %, and a Kjeldahl nitrogen content of 0-0.04 wt %, wherein said agarose forms a gel which has a gel strength of at least 1200 g/cm 2 at 1.0 wt agarose concentration, exhibits substantial absence of DNA binding in 0.07 M or less tris acetate buffer, and an electroendosmosis of 0.05 or less at 1.0 wt % agarose concentration, and said agarose bead is coated with a layer of agarose from about 0.05 mm to 5.0 mm in thickness.
