Abstract
Methods of regenerating apatite surfaces, for example after purification of a target analyte. The methods include, for example, regeneration that can involve contacting the apatite solid surface with a buffered calcium solution and a zwitterionic buffer, then contacting the apatite solid surface with a phosphate buffered solution, and then contacting the apatite solid surface with a solution comprising a hydroxide.
