Hydroxyapatite 40nm 96 Percent For Protein Separation - China

Item No.

NNB02 Acicular Particle size: 40nm, 96% Package(aluminum foil bag): 50g/bag; 1kg/bag; 10kgs/bag Applications: Protein separation composition of hydroxyapatite is Ca10 (PO4) 6 (OH) 2, Ca / P of 1.67, but due to the processes of preparation, the real composition is quite complex.

HA is hexagonal crystal, is L6PC symmetric and P63 / m space group, its structure is a hexagonal prism, with the c axis perpendicular to the plane is a hexagon, a, b-axis angle of 120o;, its lattice parameters is a = 9.43 ~ 9.38Å;, c = 6.88 ~ 6.86Å;, z = 2, unit cell contains 10 Ca2+, 6xPO43-and 2 of OH-.

HA surface has a surface of several possible states: (1) When a crystalline surface OH, OH with 2 Ca (Ⅱ) ion is connected, when the HA in aqueous solution, the position of this surface at least in a moment OH vacancy, by two Ca (Ⅱ) ion with a positive charge, forming a suction position, this position can be adsorbed PO43-or phosphate groups on the macromolecule or a carboxyl group.

(2) When the Ca ions in the surface of the crystal, since Ca (Ⅰ) and 6 charged negatively charged O atom, when the HA in aqueous solution, the surface of Ca (Ⅰ) position vacancies in a moment, in Ca (Ⅰ) position to form a strong adsorption sites, can absorb Sr3 +, K + and other cations and the group of protein molecules, and in the Ca (Ⅱ) position is the formation of a weaker adsorption sites.

(3) PO43-in crystal surface, H2O through hydrogen bonding with PO43-ions.
