Biological Activity

[Description]:

Hel 13-5 is a monomeric synthetic peptide based on the N-terminal segment of human SP-B. Hel 13-5 mainly is a-helical and consists of 13 hydrophobic and 5 hydrophilic amino acid residues. Hel 13-5 can be used in combination with phospholipids for developing pulmonary surfactant model systems[1][2].
