It relates to the agent. More specifically, the present invention relates to a novel filler that has high chemical stability with respect to a high-concentration alkaline aqueous solution, is excellent in hydrophilicity, and can be used for protein separation and purification.
- Chromatographic fillers used for protein adsorption, separation, and purification include inorganic fillers typified by silica compounds and the like, and organic fillers composed of organic polymers.
- Organic fillers are synthetic fillers that use synthetic compounds represented by styrene, (meth) acrylic acid esters, and (meth) acrylamides, and natural polysaccharides such as agarose, dextran, and mannan. Broadly divided into system fillers.

This cleaning method is recommended as a guideline by the US Food and Drug Administration, and is an effective method for initial and re-use. In other words, it is common practice in GMP facilities that purify pharmaceutical proteins to clean the inside of the column device for each batch used. Also, when there is a batch interval, the device may be stopped by enclosing a sodium hydroxide solution diluted to 0.1N with 0.01N force. Furthermore, in order to remove abnormal proteins such as prions, it is also necessary to wash with a higher concentration (for example, 2 N concentration) of sodium hydroxide aqueous solution.
- a higher concentration for example, 2 N concentration
- the synthetic filler is hard (high mechanical strength), it has the advantage that it is suitable for high-speed and high separation, and has the advantage of high hydrophilicity, while being further alkaline. At present, development of synthetic fillers with resistance is expected.

- a hydrophilic base material for chromatography intended for separation and purification of biopolymers is a target biopolymer when eluted with a neutral eluent having a salt concentration of 0.1 mol Z1. It is preferable that the filler is eluted without any interaction. That is, if the hydrophilic substrate is a porous substrate, it elutes in the order of molecular force with the largest molecular size based on the principle of size exclusion chromatography (hereinafter abbreviated as SEC). It is preferred that all molecules elute with an elution volume that is less than or equal to the total eluate volume.
- the physical properties of the hydrophilic substrate can be substantially defined by the pore physical properties, mechanical strength, particle size distribution and shape.
- the physical properties of the pores can be largely defined by the pore size distribution and the porosity. Appropriate pore properties depend on the separation purpose, method and molecular size of the target polymer.

Therefore, the porosity is preferably 95% or less.
- the base material of the packing material for high performance liquid chromatography for analytical purposes is preferably 80% or less. If the particle size is reduced, the pressure loss per column height of the packed column increases, and it becomes necessary to increase the mechanical strength.
- the packing material in order to pass the eluent at an appropriate flow rate, the packing material must have high mechanical strength, and the porosity and particle size must be adjusted so that the pressure loss is not increased more than necessary. . If the shape of the packing material is not spherical, the packing material forms a bridge when packed in the column, creating a gap, and packing the most densely. I can't fill it. Therefore, practically, the elution peak shape is asymmetrical, the peak width is widened, and the column has low performance. Therefore, the shape of the filler is preferably spherical.

- This is a filler with fixed ion exchange groups. Most of the physical properties of such fillers depend on the substrate.
- the salt concentration of the eluent is changed by introducing an ion exchange group, the osmotic pressure changes between the inside and outside of the particle. This action causes the filler to swell at low salt concentrations and shrink at high salt concentrations.
- protein ion-exchange chromatography a method that gradually increases the salt concentration and sequentially elutes protein forces with low interaction is frequently used.
- the volume of the column bed changes greatly, and the packing state changes each time, and separation with good reproducibility is not achieved.
- the magnitude of the swelling / shrinkage ratio is determined by the strength (hardness) of the base matrix (skeleton) and the ion exchange capacity. In general, the greater the ion exchange capacity, the greater the effect. Therefore, it is better that the ion exchange capacity, which makes the base matrix difficult to swell and shrink, is not larger than necessary. Specifically, an appropriate range for the ion exchange capacity is 30 to 300 meqZl.
- the elution method of ion exchange chromatography is generally performed by gradually increasing the salt concentration as described above, or gradually elution of the eluent from the pH at which the target solute binds to the ion exchange group to the repulsive pH. There are methods of changing pH or a combination of both.
