    • PEP 13, 31 and 60 were purchased from Sigma-Aldrich, Japan, and Biomer Technology, CA, USA. The sequences of amino acids for these peptides are identical to those of peptides we reported earlier and referred to as MAT 13, 31, and 60, respectively.

    • 9 The extracted peptide solution was dried by Speed Vacuum and kept at -20 °C for further analysis by the MALDI mass spectrometer.The dried samples were mixed with 10 μL of the solution containing 50% acetonitrile and 0.1% TFA. The digested sample (0.5 μL) was deposited on a MALDI-plate followed by the addition of 0.5 μL of a matrix consisting of 5 mg/mL of α-cyano-4-hydroxycinnamic acid (CHCA) in 50% acetonitrile and 0.1% trifluoroacetic acid (TFA).
