1.1 Bio-Gel HT Fully Hydrated
Hydroxyapatite
Bio-Gel HT hydroxyapatite, prepared by the method
of Tiselius, et al., 22 is shipped suspended in 10 mM sodi-
um phosphate buffer containing 0.02% NaN

. This mate-
rial gives excellent resolution at a high flow rate (see
Table 1) because of its large particle size. Bio-Gel HT
hydroxyapatite has a shelf life of at least 1 year when
stored at 4 °C in the shipping buffer.
1.2 Bio-Gel HTP Powder
Bio-Gel HTP hydroxyapatite is the Tiselius material
which has been dried by a unique process developed at
Bio-Rad. It may be stored without refrigeration, and,
when resuspended in buffer, it has the same properties as
Bio-Gel HT hydroxyapatite.
