Research Abstract |
To find a receptor molecule of the ischemic heart-homing peptide, the affinity screening is necessary and the carrier must play a key role. FG beads, which are 200nm in diameter and consisted of magnetic ferrite covered by Poly-glycidylmethacrylate resin, are used as affinity carrier to bind the ischemic heart-homing peptides. The condition to bind the peptide to FG beads was optimized, and the combination of the acetylene peptide at N’-terminus and azide FG beads worked not destroy tertiary structure of peptide. Then, pull-down assay with the affinity beads was performed to find receptors for the homing peptide from ischemic heart tissue of rats, which is made by temporary occlusion of leftcoronary artery.
