Bioactivity | KALA is an amphiphilic peptide that forms an α-helical structure at physiological pH. KALA modifies a plasmid DNA-encapsulating liposomal membrane and is used as a fusogenic peptide in order to achieve effective liver targeting and transfection of DNA via galactose receptors[1]. | ||||||
Invitro | When a plasmid DNA-encapsulating liposomal membrane is modified with the KALA peptide, transgene expression and immune activation are facilitated in bone marrow-derived dendritic cells (BMDCs)[1]. | ||||||
