HEK293T and U87 cells were maintained in DMEM (Gibco) supplemented with 10% foetal bovine serum (FBS, LabTech) and 100 U/ml penicillin plus 100 μg/ml streptomycin (Pen/Strep; Gibco). THP‐1 cells were maintained in RPMI (Gibco) supplemented with 10% FBS and Pen/Strep. THP‐1‐IFIT‐1 cells that had been modified to express Gaussia luciferase under the control of the IFIT‐1 promoter were described previously (Mankan et al, 2014). THP‐1 Dual Control and cGAS−/− cells were obtained from Invivogen. Lopinavir (LPV), darunavir (DRV), nevirapine (NVP) and raltegravir were obtained from AIDS reagents. STING inhibitor H151 was obtained from Invivogen. JAK inhibitor ruxolitinib was obtained from CELL guidance systems. PF‐74 was obtained from Sigma. Lipopolysaccharide, IFNβ and poly I:C were obtained from PeproTech. Sendai virus was obtained from Charles River Laboratories. Herring testis DNA was obtained from Sigma. cGAMP was obtained from Invivogen. Anti‐IFNα/β receptor and control IgG2A antibodies were obtained from PBL Interferon Source and R&D systems, respectively. For stimulation of cells by transfection, transfection mixes were prepared using lipofectamine 2000 according to the manufacturer's instructions (Invitrogen).

THP-1 dual cells were maintained in RPMI (Gibco) supplemented with 10% FBS, Pen/Strep, 25 mM HEPES (Sigma), 10 µg ml−1 of blasticidin (Invivogen) and 100 μg ml−1 of Zeocin (Invivogen). GHOST cells stably expressing CD4, CCR5, CXCR4 and the green fluorescent protein (GFP) reporter gene under the control of the HIV-2 long terminal repeat, were maintained in DMEM supplemented with 10% FBS, and antibiotics, G418 (500 μg ml−1) (Thermo Fisher), hygromycin (100 μg ml−1)(Invitrogen) and puromycin (1 μg ml−1) (Millipore). Lipopolysaccharide, IFNβ, IL-1β and poly I:C were obtained from Peprotech. Herring testes (HT) DNA was obtained from Sigma. For stimulation of cells by transfection, transfection mixes were prepared using lipofectamine 2000 (Invitrogen) in Optimem (Thermo Fisher). HT DNA and poly I:C concentration used are stated on each figure.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
