Abstract:
An assembly for use in biological assays containing an integral ceramic core and, partially abutting the core, a sheath. The ceramic core has a mean pore size of from about 1 to about 400 microns, an apparent porosity of from, about 25 to about 60 percent, a hydrophilic surface, a length of from about 10 to about 200 millimeters, and a wicking rate of at least about 20 millimeters per minute; the sheath has a wicking rate of less than 5 millimeters per minute.
