Human breast epithelial MCF-10A cells, mouse macrophage Raw 264.7 cells, and human adult keratinocyte HaCaT cells were obtained from the American Type Culture Collection. All cells have been passaged directly from the original low-passage stocks and were used before passage 30. The cells were also tested within the last three months for correct morphology under microscope and tested to detect any mycoplasma contamination using an e-Myco plus mycoplasma PCR detection kit (iNtRON Biotechnology, Seongnam, Korea). Cells were maintained at 37 °C in a humidified atmosphere of 5% CO2 and 95% air.

PBMCs derived from apheresis were further enriched by density gradient centrifugation in lymphocyte separation medium (Lonza, Basel, Switzerland). The PBMCs were incubated for 2 h at 37 °C in X-VIVO15 medium (Lonza) in a plastic flask, and adherent cells were cultured in X-VIVO15 medium containing 2 % heat-inactivated autologous plasma, 1000 U/mL human interleukin-4 (IL-4, GMP-grade, Strathmann Biotec AG, Hannover, Germany), and 500 U/mL granulocyte macrophage colony-stimulating factor (GM-CSF, GMP-grade, GENTAUR Belgium BVBA, Kampenhout, Belgium). On day 6, loosely attached or floating immature DCs were collected. The immature DCs were stored in the gas phase of a liquid nitrogen tank until use. No bacteria, fungus, mycoplasma, or endotoxin contamination were detected in any cell culture products. The Gram’s iodine stain method was used for bacteria contamination evaluation. The detection of bacteria and fungus contamination was further performed by a growth-based rapid microbiological method with the BacT/ALERT automatic culture system (bioMerieux SA, Marcy I’Etoile, France). The detection of mycoplasma contamination was performed using a PCR-based method (e-Myco plus mycoplasma PCR detection kit, iNtRON Biotechnology, Kyungki-Do, Korea). The endotoxin contamination was determined using a Limius Amebocyte Lysate QCL-1000 Endotoxin test (Lonza).

Lentiviruses were generated using pLKO.1 or pLKO.2 vectors (Sigma-Aldrich, obtained through the University of Colorado Functional and Genomics Shared Resource, USA, Supplementary Table S2) and were used to transduce cells as previously described11 (link). Cells were selected in 1 µg/mL puromycin. All cells were routinely monitored for mycoplasma contamination using e-Myco plus Mycoplasma PCR detection kit (iNtRON biotechnology) according to the manufacturer’s directions.

BSR (single cell clone of BHK-21 cells, species Mesocricetus auratus, provided by Polly Roy, LSHTM, UK) were maintained in Dulbecco's modified Eagle's medium (DMEM), high glucose, supplemented with l-glutamine (1 mM), antibiotics, and fetal bovine serum (FBS) (5%), at 37°C and 5% CO2. Cells were verified as mycoplasma-free by PCR (e-Myco plus Mycoplasma PCR Detection Kit, iNtRON Biotechnology). Cells were seeded to achieve 80% confluence on the day they were infected with virus stocks listed in (23 (link)), based on GDVII isolate NC_001366 with three nucleotide differences present in WT and mutant viruses (G2241A, A2390G and G4437A; nt coordinates with respect to NC_001366). All infections, except for plaque assays, were carried out at a MOI of 3 in serum-free media, or media only for the mock-infected samples. After incubation at 37°C for 1 h, inoculum was replaced with serum-free media supplemented with FBS (2%), and infected cells were incubated at 37°C until harvesting or further processing.

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.
