Embodiment 1

[0196] (i) Suspension polymerization of porous particles

[0197] Add 8.52 g of polyvinyl alcohol (PVA-217 manufactured by Kuraray Co., Ltd.), 2.13 g of sodium lauryl sulfate (EMAL10G manufactured by Kao Corporation), and 4.26 g of sodium carbonate to 4091 g of pure water, and stir overnight to prepare an aqueous solution (S-1- 1). Furthermore, another 30 g of (S-1-1) was extracted on the day of polymerization, and 2.13 g of sodium nitrite was dissolved in the remaining (S-1-1) to prepare an aqueous solution (S-2-1).

[0198] Next, 125 g of glycerin dimethacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd.), 17.9 g of glycidyl methacrylate (manufactured by Mitsubishi Rayon Co., Ltd.), and 35.9 g of glycerin monomethacrylate (manufactured by NOF Corporation) were dissolved in 2 - 86.4 g of octanone (manufactured by Toyosei Co., Ltd.) and 253 g of acetophenone (manufactured by Wako Pure Chemical Industries, Ltd.) were prepared as a monomer solution. In addition...

Embodiment 2

[0240] In the suspension polymerization of Example 1, except that the stirring speed was set to 300 rpm, the same procedure was carried out to obtain porous particles 2, and the affinity chromatography formed by ligand-bonded porous particles having a ring-opening epoxy group was produced and evaluated. Filler 2 (A-2) was used. The results are shown in Table 2. The epoxy group content of the porous particles 2 was 0.45 mmol / g. (A-2) has a particle size of 31 μm, a pore volume of 1.438 mL / g, and a specific surface area of ​​132 m 2 / g, the volume average pore diameter is 110nm. The elastic modulus is 6.4MPa. The dynamic binding capacity of protein (human IgG antibody) is 40mg / mL, and the pressure flow rate is 1100cm / hr.

Embodiment 3

[0242] (i) Suspension polymerization of porous particles

[0243] Add 0.600 g of polyvinyl alcohol (PVA-217 manufactured by Kuraray), 0.030 g of sodium lauryl sulfate (EMAL10G manufactured by Kao Corporation), and 1.50 g of sodium sulfate to 300 g of pure water, and stir overnight to prepare an aqueous solution (S- 1-2). Furthermore, another 5 g of (S-1-2) was extracted on the day of polymerization, and 0.150 g of sodium nitrite was dissolved in the remaining (S-1-2) to prepare an aqueous solution (S-2-2).

[0244]Next, 8.19 g of glycerin dimethacrylate (manufactured by Shin-Nakamura Chemical Industry Co., Ltd.), 3.51 g of glycidyl methacrylate (manufactured by Mitsubishi Rayon Co., Ltd.) were dissolved in 6.25 g of 2-octanone (manufactured by Toyosei Co., Ltd.) and phenylethyl ether. Ketone (manufactured by Wako Pure Chemical Industries, Ltd.) 18.3 g was prepared as a monomer solution. In addition, when the total mass of monomers is 100 parts by mass, the number of parts of...

Description

technical field [0001] The present invention relates to a filler for affinity chromatography. In particular, it relates to a packing material for affinity chromatography useful for protein purification, comprising porous particles having a high dynamic binding capacity for proteins and excellent pressure characteristics. Background technique [0002] Affinity chromatography plays an important role in the research, development and manufacture of proteins including monoclonal antibodies. A filler for affinity chromatography generally includes a solid-phase support having a ligand that selectively binds to a target molecule. In terms of affinity chromatography, the ligands on the solid-phase support have high selectivity for the target molecule, so compared with other chromatography methods such as ion chromatography, gel filtration chromatography, reversed-phase liquid chromatography, etc. Excellent efficiency and high-speed and economical purification.
