- the sample containing a plurality of substances may be composed entirely of known compounds, may be composed of partially novel compounds, or may be composed entirely of novel compounds. There may be. However, according to the search for ligand target molecules or recent advances in proteome analysis, it is desirable that all of these structures be mixtures of known compounds.

- the binding between molecule A and hydrophilic spacer is performed, and the hydrophilic spacer is bonded to solid phase.
- a hydrophilic spacer may be bound to molecule A, and then their complex may be bound to a solid support, or a hydrophilic spacer may be bound to the solid support before binding molecule A.
- Whether or not the molecule A is immobilized on the solid phase carrier may be determined based on the coloration based on the specific structure or substituent contained in the molecule A or an arbitrary group previously bonded or introduced to the molecule A. It can be confirmed using a reaction or the like. For example, an amino group-recognition reaction can be used.

- the liquid is preferably used. If the sample does not contain molecule B, identify and analyze the molecules (multiple types may exist) that did not show a specific interaction with molecule A in step (3). If the sample contains molecule B, identify and analyze molecule B (there may be multiple types) that showed a specific interaction with molecule A in step (3).
- the method of contacting the sample with the solid phase carrier is not particularly limited as long as molecule B in the sample can bind to molecule A immobilized on the solid phase carrier.
- This step can be appropriately changed depending on the type of the solid phase carrier to be used, the type of the immobilized molecule A, and the like.However, various methods commonly used in the art for identifying low molecular weight compounds or high molecular weight compounds are used.

For example, when a column packed with a bead resin on which molecule A is immobilized is used as the solid-phase carrier on which molecule A is immobilized (step (1)), the subsequent addition of the sample results in step (2)) Bind molecule B to molecule A.
- the bound molecule B is dissociated from the molecule A by a treatment such as changing the polarity of the buffer solution or adding an excess of the molecule A, and then is identified, or the surface is directly bound with the molecule A on the solid phase. It can also be identified by extraction with an activator or the like. Specific examples of the identification method include known methods such as electrophoresis, immunoplotting using immunological reaction, immunoprecipitation, chromatography, mass spectrum, amino acid sequencing, and NMR (especially for small molecules). It will be implemented by the above method and in combination of these methods.
- the step of identifying a molecule that does not bind to the molecule A can also be performed according to the above-described method for identifying a molecule that binds to the molecule A.However, since the molecules contained in the flow-through fraction of the force ram are targeted for identification, It is preferable to carry out treatments such as concentration and rough purification in advance before entering the identification step. Each molecule is identified based on the obtained data and existing reports, and whether or not it is the target molecule of molecule A is determined.
