体外研究
(In Vitro)

FSL-1 significantly reduces HSV-2 replication in vitro. FSL-1 reduces HSV-2 replication in human vaginal epithelial cells (EC)[1].
FSL-1 induces significant resistance to experimental genital HSV-2 infection through elaboration of a specific cytokine response profile[1].
FSL-1 enhances phagocytosis of bacteria by macrophages through a Toll-like receptor 2-mediated signalling pathway[1][2].

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

Cell Viability Assay[1]

Cell Line: V11I, V12I or V19I immortalized human vaginal EC
Concentration: 6 μg or 0.1 μg
Incubation Time: Added at 24, 6 or just prior to HSV-2 inoculation (104pfu/well)
Result: The 6 μg does produced significant reductions when delivered at 24 or 6 h prior to HSV-2 inoculation. The 0.1 μg dose produced reduced HSV-2 replication at 24 or 6 h prior to viral challenge.

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide Details
Negative (lt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, add NH4OH (lt;50 μL).
3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0) 1.;;Try to dissolve the peptide in water first.
2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
