L-α-グリセロホスホリルコリンの水溶液を氷水浴中で冷却した。次に、L-α-グリセロホスホリルコリンの4倍当量の過ヨウ素酸ナトリウムを添加した後、三塩化ルテニウムを触媒量添加し、3時間攪拌し、反応させた。次に、メタノールを添加して、さらに30分間攪拌した後、ろ過することにより沈殿を除去した。さらに、減圧濃縮した後、減圧乾燥し、化学式
実施例1の表面処理ウェルプレート及び未処理のウェルプレートに蛋白質を吸着させ、直接BCA法を用いて、蛋白質の吸着量を定量した。評価に用いた蛋白質は、アルブミン(Mw=69000、pI=4.9)、γ-グロブリン(Mw=150000、5.0<pI<9.5)、リゾチーム(Mw=14000、pI=11.0)(以上、Sigma社製)の三種類である。
脱水エタノール/脱水クロロホルム混合液中、白金触媒(H2PtCl6・6H2O)の存在下で、化合物Bと、化学式
アミン当量が144g/molであるジアミンタイプのアミノ変性ポリシロキサン(図5参照)のメタノール溶液中に、アミノ変性ポリシロキサンの2倍当量の化合物Aを添加した後、化合物Aの1.2倍当量のトリアジン型脱水縮合剤DMT-MM(国産化学社製)を添加し、室温で3時間攪拌して反応させ、化合物D(ホスホリルコリン基を有するポリシロキサン)を得た(図6参照)。
