Abstract
Disclosed are compositions and methods for regenerating or reducing the deterioration of an apatite solid surface during, or subsequent to, a chromatographic procedure for purifying a target molecule from a sample, by treating the apatite solid surface with a buffered calcium solution, followed by a phosphate buffered solution, followed by an alkaline hydroxide. The buffered calcium solution, phosphate buffered solution, and alkaline hydroxide can be applied subsequent to a bind and elute or flow through purification procedure. The methods provide an increase in resin mass and/or particle strength compared to prior methods.
