生物活性

LL-37, human TFA is a 37-residue, amphipathic, cathelicidin-derived antimicrobial peptide, which exhibits a broad spectrum of antimicrobial activity. LL-37, human TFA could help protect the cornea from infection and modulates wound healing[1][2][3].

体外研究
(In Vitro)

LL-37,human TFA (1 -20 μg/mL;24 h) 影响HCECs迁移[2]
LL-37,human TFA (0.0001-5 μg/mL;6-24 h) 影响 HCECs 中的细胞因子分泌[2]
LL-37,human TFA (1-100 μg/mL;24 h) 在一定浓度下对 HCECs 表现出剂量依赖性细胞毒性超过 10 μg/mL[2]

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

Cell Migration Assay [2]

Cell Line: Human corneal epithelial cell (HCEC)
Concentration: 1, 2.5, 5, 10 and 20 μg/mL
Incubation Time: 24 hours
Result: Dose-dependently stimulated HCECs migration but showed no effect on cells proliferation.

Cell Viability Assay[2]

Cell Line: Human corneal epithelial cell (HCEC)
Concentration: 0.0001, 0.001, 0.01, 0.1, 0.5, 1, and 5 μg/mL
Incubation Time: 6 and 24 hours
Result: Dose-dependently increased IL-8, IL-6, IL-1β and TNF-α secretion at 6 and 24 hours in HCECs.
体内研究
(In Vivo)

LL-37, human TFA (0.4-2.0 mg/kg;气管内注射一次) 改善 MRSA 诱导的小鼠肺炎[3]

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

Animal Model: 6-8 week-old C57BL/6 mice with MRSA-induced pneumonia[3]
Dosage: 0.4, 0.8, 1.2, 1.6 and 2.0 mg/kg
Administration: Intratracheal injection; 0.4-2.0 mg/kg once
Result: Decreased IL-6 and TNF-α release to attenuated MRSA-induced pneumonia of testing 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.
