  Design and synthesis of novel hydrophilic spacers for the reduction of nonspecific binding proteins on affinity resins

  摘要：

  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.

  本发明提供了一种抑制分子之间非特异性相互作用的方法，其特征在于在将分子固定到固相载体并分析与固相上特异性相互作用的分子之间的过程中，调节固相载体中固相表面的疏水性质，特别是在将分子固定到固相载体时，交错放置了亲水性间隔物，该方法使得能够抑制分子之间的非特异性相互作用，并减少对固相的非特异性吸附。
