Hydroxyapatite (Ca5(PO4)3OH)2 is a form of calcium phosphate used in the chromatographic separation of biomolecules. Sets of five calcium doublets (C-sites) and pairs of -OH containing phosphate triplets (P-sites) are arranged in a repeating geometric pattern Hydroxyapatite Chromatography Ca ⁺⁺ Pure-HA is a hydroxyapatite resin used in the chromatographic separation of biomolecules. Key applications for use of Ca⁺⁺Pure-HA include the purification of monoclonal and polyclonal antibodies, including IgG, IgA, IgM, antibody fragments, fusion- and phosphoproteins, and the separation of single-stranded and double-stranded DNA The principle of affinity chromatography is based on the property of specific and non-covalent binding of proteins to other molecules, referred to as ligands' Enzymes bind specifically to ligands such as substrates or cofactors. The technique involves the use of ligands covalently attached to an inert and porous matrix in a column. The immobilized ligands act as molecular fishhook to selectively pick up the desired protein while the remaining proteins pass through the column Hydroxyapatite (HA) column chromatography, originally introduced by Tiselius et al. [I], is a powerful technique for separation of proteins, nucleic acids and viruses [2-41. In many instances, the chromatography is carried out by using a linear molarity gradient of potassium or sodium phosphate buffer zat pH isoelectric6.8

Hydroxyapatite, also called hydroxylapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3, but it is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities. Hydroxyapatite is the hydroxyl endmember of the complex apatite group. The OH− ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxyapatite powder. The purpose of this section is to provide developmental purification strategies for recombinant proteins on a column of hydroxyapatite and then to optimize them for repeated purification cycles using effect additives. Surface neutralization solutions (SNS) (patent pending) and/or the addition of calcium ions reduce the solubility of hydroxyapatite.
