Scientific Background | KKKKKKKKKK is a synthetic research peptide in the nona-lysine (K9) cationic peptide category. This product is a homopolymeric nona-lysine peptide. Lysine-rich sequences are strongly cationic and have been used as protein-transduction or nucleic-acid-associated motifs. Published work comparing a nine-polylysine domain with HIV Tat demonstrated cellular transduction capability, but activity depends on cargo, formulation, concentration, and experimental context. |
Experimental Notes | The exact supplied sequence and modification state should be used when interpreting published results. Activity reported for a parent peptide, labeled derivative, formulation, species variant, or related analog should not automatically be assigned to this construct. |
