Description

HLF1-11, a human lactoferrin-derived peptide, is a broad spectrum antimicrobial agent. HLF1-11 inhibits human MPO activity. HLF1-11 also directs GM-CSF-driven monocyte differentiation toward macrophages, and enhances immune responses[1][2].

In Vitro

hLF1-11 (1, 10, and 100 μg/mL) directs differentiation of monocytes toward a macrophage subset during granulocyte-macrophage colony-stimulating factor (GM-CSF)-driven monocytes differentiation[2].
hLF1-11 (0.5-250 μg/mL) inhibits human MPO activity[3].
hLF1-11 (100 μg/mL, 90 min) inhibits ROS induction induced by LPS in monocytes[3].
hLF1-11 (8-34 μΜ, 2 h) is active against fluconazole-resistant C. albicans[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

hLF1-11 (20 mg/kg, injected into the debrided tibial cavity) shows ability against MRSA osteomyelitis in rabbits[4].
hLF1-11 (40 μg/kg, i.v.) is active against C. albicans-infected mice[6].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Rabbits inoculated with CFU MRSA[4]
Dosage: 20 mg/kg
Administration: Injected into the debrided tibial cavity
Result: Reduced bacterial load compared to controls, and reduced the radiological and histopathological score.
Animal Model: Neutropenic mice challenged i.v. with C. albicans
Dosage: 40 μg/kg
Administration: Intravenous injection (i.v)
Result: Reduced serum TNFα and IL-6 in infected mice.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
