HEK293T cells (Invitrogen, Carlsbad, CA) and the HeLa cell line TZM-bl (Obtained through NIH AIDS Reagent Program, Division of AIDS, NIAID, NIH, from John C Kappes, Xiaoyun Wu and Tranzyme (Catalogue No. 8129)) were cultured in Dulbecco’s modified Eagle’s medium (DMEM) (Gibco, Waltham, MA) supplemented with 10% fetal calf serum (FCS) (Gibco).
Monocytes were purified from peripheral blood mononuclear cells by positive selection using anti-CD14 magnetic beads as outlined by the manufacturer (Miltenyi Biotech, Gladbach, Germany) with the exception of using phosphate-buffered saline (PBS) supplemented with 1% (v/v) human AB serum (Sigma Aldrich, St Louis, MO) and 1 mmol/l ethylenediaminetetraacetate (EDTA) (Sigma Aldrich) at 4°C. MDDCs were generated by culturing purified monocytes in Roswell Park Memorial Institute (RPMI) 1640 supplemented with 10% fetal calf serum (FCS), IL-4 (1,000 U/ml) and GM-CSF (1,000 U/ml) (Biosource, Carlsbad, CA) for 24 hours. MDMs were made by plastic adherence of monocytes in serum free media for 1 hour before supplemented with RPMI 1640 media containing human AB serum (Sigma Aldrich), which brought the final concentration of human serum to 10%. MDMs were used after 7 days of differentiation for experiments.

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.
