Tubulin and actin often bind nonspecifically to affinity chromatography resins, complicating research toward identifying the cellular targets. Reduction of nonspecific binding proteins is important for success in finding such targets. We herein disclose the design, synthesis, and effectiveness in reduction of nonspecific binding proteins, of novel hydrophilic spacers (2-5), which were introduced between matrices and a ligand. Among them, tartaric acid derivative (5) exhibited the most effective reduction of nonspecific binding proteins, whilst maintaining binding of the target protein. Introduction of 5 on TOYOPEARL reduced tubulin and actin by almost 65% and 90% compared to that without the hydrophilic spacer, respectively, with effective binding to the target protein, FKBP12.

The present invention provides a method of suppressing the nonspecific interaction between molecules, characterized in that in a process to immobilize a molecule onto a solid phase carrier and analyze the specific interaction between the molecule and a molecule that specifically interacts with the molecule on the solid phase, the hydrophobic property of the solid phase surface in the solid phase carrier is regulated, particularly a hydrophilic spacer is interlaid at the time of immobilization of the molecule onto the solid phase carrier, which method makes it possible to suppress the nonspecific interaction between the molecules, and to reduce nonspecific adsorption to the solid phase.
