Biological Activity

HIV-1 |
A cell-cell fusion assay reveals that the effective concentration for achieving 50% inhibition (IC50) of Enfuvirtide is 23 ± 6 nM[2]. IFN-λs (1, 2, or 3) or the antiretrovirals (AZT, Efavirenz, Indinavir, and Enfuvirtide) significantly inhibita the expression of HIV p24 antigen and Gag gene in macrophages. IFN-λs (1, 2, or 3) also enhanced the anti-HIV (Bal) effect of AZT, Efavirenz, Indinavir, and Enfuvirtide[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2 mg/mL (0.45 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
For infection with the resistant HIV strains, 7-day-cultured macrophages (105 cells/well in 96-well plates) are incubated with or without IFN-λ1, λ2, or λ3 (100 ng/mL each) and/or anti-HIV drugs: Azidothymidine (AZT) 10 pM; Efavirenz 100 pM; Indinavir 10-3 pM, and Enfuvirtide 10 nM for 24 h. Cells are then infected with different strains of HIV (6 ng p24/well) for 2 h. After washed three times with plain DMEM, cells are cultured with fresh 10% DMEM containing IFN-λs and/or antiretroviral drugs. For HIV Bal infection, culture supernatant is harvested at day 8 post infection for RT and p24 assays. Infected and untreated cells served as controls. HIV Gag gene expression in infected cells is also examined at day 8 post infection. For anti-HIV drug-resistant virus (A012 G691-6 or TC49) infection, culture supernatant is harvested for HIV p24 protein by ELISA at days 3, 5, 7, and 10 postinfection. The cell cultures are replaced with the fresh media supplemented with IFN-λ1, λ2, or λ3 and/or the antiretrovirals every 2–3 days. The culture supernatant collected at day 10 postinfection is also subjected to RT assay[3].
