法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a packing material for a chromatography column in which the inner surface of the bore and the outer surface of the bore have essentially different functions, and a method for producing the packing material.

て説明する。Packing materials with different functions on both the inner and outer surfaces have the potential for more diverse and advanced applications than conventional fillers with single functions. It has been applied to protein removal treatment as a pretreatment for analysis, and has achieved revolutionary effects. The filler produced by the method of the present invention has various possibilities, but for the sake of simplicity, the following explanation will focus on protein removal pretreatment.

に非常に労力を要するものである。[Prior Art] Chromatography, particularly high performance liquid chromatography (hereinafter referred to as HPLC), is widely used as a very effective means for analyzing drugs and the like in biological samples containing proteins such as serum. In this HPLC analysis, reversed-phase packing materials are usually used, but proteins in the sample are irreversibly adsorbed to this packing material, causing serious problems such as clogging the column. Therefore, it is essential to pre-process protein removal before performing HPLC analysis. Such preprocessing requires a lot of effort because it is performed manually.

質を吸着する能力を持たない。However, recently, the inner surface of the filler has been made hydrophobic,
In addition, a new type of packing material was developed that made the outer surface hydrophilic to make it difficult for proteins to be adsorbed.This was used as a pretreatment column (along with a column switching valve) (incorporated into PLO for online protein removal processing). It has become possible to directly analyze biological samples such as those mentioned above.For example,
Examples include inventions described in Japanese Patent Application Laid-open No. 8-223062 and Japanese Patent Application Laid-open No. 60-56256. In particular, according to the latter invention, silane (O
DS) is used as a filler coated with protein. This protein-coated ODS is OD
It is prepared by injecting an appropriate inert protein solution into a column packed with S and actively adsorbing the protein onto the column. Since the protein is larger than the pore size of ODS, it cannot enter the pore, and therefore the octadecyl group introduced from the beginning remains on the inner surface of the pore, preserving hydrophobicity. On the other hand, the outer surface is covered with adsorbed proteins and no longer has the ability to adsorb proteins.

、ここで各成分ごとに分離されることになる。To perform protein removal pretreatment using a column made of this packing material, a suitable buffer solution is fed to the column, and then a sample such as serum to be analyzed is injected. At this time, components such as drugs that have low molecular weight and relatively high hydrophobicity are adsorbed and retained by the octadecyl groups on the surface of the pores, but on the other hand, proteins in the sample are large and therefore cannot be stored inside the pores. Since it cannot enter the column and is not adsorbed on the outer surface, it will be eluted from this column in a short time. Then, when the outlet side flow path of this pretreatment column is connected to the separation column and the mobile phase (eluate) is switched to stronger conditions, the retained components such as drugs are separated from this pretreatment column. , to a separation column, where each component is separated.
このようにして調製されたタンパク質コートODSは短

されている。However, if used for a long period of time, the proteins that were initially adsorbed may elute and flow out and adsorb onto the separation column, causing its deterioration.Also, when the column is held, it may cause putrefaction due to microorganisms, etc. Problems remain, including the need for sufficient caution.
除タンパク質前処理の別の方法に、特開昭61−651
59号公報に記載されたピンカートンらの方法もある。Another method for protein removal pretreatment is disclosed in JP-A-61-651.
There is also the method of Pinkerton et al. described in Publication No. 59.
この方法は充填剤の製法に特徴があり、充填剤の出発物

、或はシリカゲルに即知の方法でグリセロイルプロピル
基を導入してもよい)あるいは多孔性ガラスを用いる。This method is characterized by the manufacturing method of the filler, and the starting material for the filler is silica gel into which glyceroylpropyl groups have been introduced (for example, commercially available from Merck).
Lichrosorb Diol can be used, or glyceroylpropyl groups can be introduced into silica gel by known methods) or porous glass can be used.

となる。An oligopeptide, typically glycylphenylalanine or glycylphenylalanyl-phenylalanine, is bonded to this via carbonyldiimidazole. As a result, the inner and outer surfaces of the filler become hydrophobic due to the phenyl group of phenylalanine. When carboxypeptidase A or chymotrypsin, which is a proteolytic enzyme, is applied to this protein, the peptide bonds on the outer surface are cleaved, the glyceroylpropyl group introduced from the beginning is exposed, the hydrophilicity is restored, and the protein is Becomes non-adsorbent.

する充填剤が得られる。However, since the enzyme is larger than the pore size of the filler, it cannot enter into the interior of the filler, so the peptides on the inner surface remain undegraded and remain hydrophobic, allowing a filler with the desired properties to be obtained. .

種々選択できる充填剤の製造方法が望まれていた。However, the filler obtained by Pinkerton's method has an interlayer point in which the hydrophobicity of the inner surface is not sufficiently satisfactory. That is, the main focus of this production method is to decompose and remove hydrophobic groups on the outer surface using a proteolytic enzyme, and therefore, hydrophobicity must be introduced in the form of a peptide. Therefore, there is a problem that the hydrophobic group is substantially limited to phenylalanine. actual,
If this column is used to pre-treat a serum sample containing phenobarbital, which is used as an anti-inflammatory agent, the hydrophobicity of phenobarbicul is not very high, so the phenobarbital will be removed before the serum proteins are sufficiently removed. Barbital may be washed away from the pretreatment column. In order to solve these problems, there has been a demand for a method for producing fillers that allows for various hydrophobic strengths to be selected.

Although it is possible to simultaneously analyze fillers and organic substances, it has not been possible to produce fillers with such properties using the above-mentioned conventional techniques.

い。The first step is to prepare a filler material consisting of a porous material with a pore size that is virtually impermeable to proteins.
A hydrophobic group having an amide bond is introduced into this raw material. Such a raw material is required to be capable of introducing a hydrophobic group having an amide bond, and that the pores of the raw material are large enough to allow the introduction of the hydrophobic group into the inside.
Substantially any filler raw material can be used as long as it meets these conditions. For example, when the raw material is a silica gel type, there is a functional group on its surface as shown in Figure 1. The reagents are reacted to form a terminal amino group, which is then labeled with R,C
OCl2 (wherein R8 is a group imparting hydrophobicity, such as a C2-C20 alkyl group or a phenyl group, etc.) is reacted, preferably in the presence of a basic catalyst such as triethylamine, to form an amide. Hydrophobic groups with bonds can be introduced on both the inner and outer surfaces of the filler in two steps. At that time, Sp, which is available as a commercial product,
herisorb 5 NH* (manufactured by Phase Sebareshing Co., Ltd.), Lichrosorb NH*
(manufactured by Merck & Co., Ltd.) is convenient because the step of forming the terminal amino group can be omitted.

ものから自由にデザインすることが可能である。This enzyme has extremely low substrate specificity compared to general enzymes and has the ability to cleave a wide variety of amide bonds. This low specificity, which can be said to be exceptional for an enzyme, made the method of the present invention possible. In other words, due to its low specificity, polymicin acylase allows the functional group that introduces hydrophobicity (R, in Figure 1) to be freely designed, thereby achieving the hydrophobicity required for the filler. It is possible to select from linear or branched alkyne groups (which may be substituted with phenyl groups, halogen atoms, nitro groups, or other hydrophobic moieties) having a C1 to C2 degree degree depending on the strength of the alkyne group. Furthermore, %R1 can be freely designed from among phenyl groups, substituted phenyl groups, and other aryl groups with various properties and performances.

めである。This is a significant advantage of the present invention over the Pinkerton method. This is because Pinkerton's method
The enzyme used is carboxypeptidase A or chymotrypsin, which is a proteolytic enzyme, and due to its high specificity, there is a serious constraint that the hydrophobic group introduced must be an amino acid, and in the end, the hydrophobic group introduced must be an amino acid. This is because only the insufficient hydrophobicity of the phenyl group can be achieved, which causes the above-mentioned problems.
