  • Patent number: 7098028
    Abstract: Described herein is the self-assembly of amphiphilic peptides, i.e., peptides with alternating hydrophobic and hydrophilic residues, into macroscopic membranes. The membrane-forming peptides are greater than 12 amino acids in length, and preferably at least 16 amino acids, are complementary and are structurally compatible. Specifically, two peptides, (AEAEAKAK)2 (ARARADAD)2, were shown to self-assemble into macroscopic membranes. Conditions under which the peptides self-assemble into macroscopic membranes and methods for producing the membranes are also described. The macroscopic membranes have several interesting properties: they are stable in aqueous solution, serum, and ethanol, are highly resistant to heat, alkaline and acidic pH, chemical denaturants, and proteolytic digestion, and are non-cytotoxic.
    Type: Grant
    Filed: March 17, 2003
    Date of Patent: August 29, 2006
    Assignee: Massachusetts Institute of Technology
    Inventors: Todd Holmes, Shuguang Zhang, Alexander Rich, C. Michael DiPersio, Curtis Lockshin
