• Molecular Weight: 949.15 (free base)
• Purity: ≥95%

Ac-IHIHIYI-NH₂ TFA (Cat No.: I040031) is a synthetic peptide composed of isoleucine (I), histidine (H), and tyrosine (Y) residues, acetylated at the N-terminus and amidated at the C-terminus, with trifluoroacetate (TFA) as the counterion. This amphiphilic sequence is often used in nanomaterial and self-assembly research due to its ability to form β-sheet structures and hydrogels. The histidine residues can participate in pH-sensitive interactions, while tyrosine contributes to aromatic stacking, making it useful in developing responsive biomaterials, drug delivery systems, and tissue engineering scaffolds.
