Briefly, CD14+ monocytes from healthy donors were cultured for 7 days to allow differentiation to MDM. MDM were stimulated in triplicate with 25 ng/mL of a single interferon (IFN-α, IFN-ε, IFN-γ or IFN-λ) or infected with 250 ng HIV-1-BAL-HSA virus. Total RNA was isolated 18 h following interferon stimulation or 6 h post infection using the RNeasy minikit (Qiagen, Hilden, Germany). Intact poly(A) RNA was purified and stranded mRNA sequencing libraries were prepared using the Illumina (San Diego, CA, USA) TruSeq Stranded mRNA Library Preparation kit (catalog No. RS-122-2101 and RS-122-2102). On an Illumina HiSeq 2500 instrument (HCSv2.2.38 and RTA v1.18.61), a 50-cycle single-read sequence run was performed using HiSeq SBS kit v4 sequencing reagents (catalog no. FC-401-4002).

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.
