Hydroxyapatite Chromatography

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. 

Ca⁺⁺Pure-HA resin has been sintered at high temperatures for increased mechanical and pH stability, allowing it to withstand the rigors of industrial-scale applications. Ca⁺⁺Pure-HA has a demonstrated dynamic binding capacity (DBC), at 5% breakthrough, of 55 mg mAb/mg resin at 5 minute residence time. 

Ca⁺⁺Pure-HA provides exceptional separation properties and unequalled selectivity and resolution for multiple classes of biomolecules. The robust nature of Ca⁺⁺Pure-HA offers the flexibility to use this resin at any stage in a process.
