OLIGOPEPTIDE SPECIFICALLY BINDING TO SCHWANN CELLS

摘要

PURPOSE: An oligopeptide specifically binding to Schwann cells is provided, which is useful for treatment of damage in nerve cells. CONSTITUTION: An oligopeptide specifically binding to Schwann cells is provided, wherein the oligopeptide has the amino acid sequence of SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3. The oligopeptide specifically binding to Schwann cell is isolated by inserting random amino acid sequences into a vector pFLITRIX containing the active portion of thioredoxin; transforming Escherichia coli with the vector pFLITRIX; culturing the transformed E. coli in an ampicillin containing IMC selection medium; adding tryptophane into the medium and culturing it to induce FLITRIX peptide; binding the transformed E. coli to Schwann cells fixed on a dish; selecting peptides specifically binding to the Schwann cells; and sequencing the selected peptides.
