SourceSynthetic construct
ActivityAntimicrobial, Antibacterial, Anti-Gram+, Anti-Gram-
Pathogen[Ref.28921993] Gram-positive bacteria: Staphylococcus aureus (MIC > 256 μg/mL), Enterococcus faecalis (MIC > 256 μg/mL);##Gram-negative bacteria: Escherichia coli (MIC > 256 μg/mL), Pseudomonas aeruginosa (MIC > 256 μg/mL)
Hemolytic Activity[Ref.28921993] 0.4%, 0.2%, 0.3%, 0.2%, 1.5%, 0.2% and 0.1% hemolysis against human red blood cells at 7.5, 10, 15, 20, 25, 30 and 40 μg/ml.
Cytotoxicity[Ref.28921993] The toxicity of KFGF toward HEK293 and HeLa cells is much less than nonaarginine (R9) by use of flow cytometry and the peptide doesn't show any cytotoxicity at 2 μM.
