| Bioactivity | Hel 13-5 TFA is a monomeric synthetic peptide based on the N-terminal fragment of human SP-B. Hel 13-5 TFA is mainly α-helical and consists of 13 hydrophobic amino acid residues and 5 hydrophilic amino acid residues. Hel 13-5 TFA can be combined with phospholipids for the development of a model system for pulmonary surfactant[1][2]. | ||||||
