Human glioma cell lines (LN229, LN319, LN444, LN751, SF188) [25 (link),26 (link),27 (link)], human normal lung bronchial epithelial BEAS-2B cells (CRL-9609, ATCC, Manassas, VA, USA), and human embryonic kidney 293T cells were cultured on adhesive cell culture dishes in DMEM medium (10-013-CV, CORNING, Corning, NY, USA) supplemented with 10% fetal bovine serum (FBS; 10437-028, Thermo Fisher Scientific, Waltham, MA, USA) and 1% Penicillin and Streptomycin (SV30010, Cytiva, Marlborough, MA, USA) under an atmosphere of 95% air and 5% CO2 at 37 °C. Colorectal cancer cell line HCT116 was maintained in McCoy’s 5A Medium with 10% FBS. All cell lines were authenticated via short tandem repeat profiling and were regularly tested for mycoplasma.
For laminin experiments, cell culture-treated plates (TPN1006, Alkali Scientific, Fort Lauderdale, FL, USA) were coated with 10 or 50 µg/mL of laminin (L2020, Sigma-Aldrich, Burlington, MA, USA) according to the manufacturer’s protocol.
For non-adhesive cell culture conditions, non-cell culture-treated plates (351143, Corning) were coated with hydrogel (Poly-HEMA; poly 2-hydroxyethyl methacrylate, P3932, Sigma-Aldrich). Poly-HEMA (20 mg/mL dissolved in 95% ethanol on a rotating wheel at 42 °C for 24 h) was added to the plates and dried overnight. The number of viable cells was determined by performing the trypan blue dye exclusion test.

Human umbilical vein endothelial cells (HUVECs, CRL-1730, ATCC), human bronchus epithelial cells (BEAS-2Bs, CRL-9609, ATCC) were used for detecting the expression of IFITM1 and secretion of interferon-ɑ/β. Madin Darby canine kidney cells (MDCK, CCL-34, ATCC) were used for plaque assay. These cell lines were cultured in DMEM (Gibco) supplemented with 10% FBS (Gibco), 100 U/mL of penicillin G and 100 μg/mL of streptomycin (Gibco) at 37 °C in a 5% CO2 incubator. The cells in passages 5~8 were seeded into six-well plates and cultured for 24 h before each experiment.

S. aureus strains MW2, a highly pathogenic and a multidrug-resistant strain was obtained from Network on Antimicrobial Resistance in Staphylococcus aureus (NARSA). Streptococcus pyogenes M1T15448 was obtained as described previously37 . Staphylococcus strain was grown in tryptic soy broth (TSB) or TS agar. Streptococcus strain was grown in Todd-Hewitt broth supplemented with 0.5% yeast extract or 5% sheep-blood TS agar. Escherichia coli strain (DH5α, BL21 DE3-pLysS) were grown in Luria-Bertani (LB) or LB agar with or without ampicillin (100 µg/ml). All bacterial culture media were obtained from Difco (BD and Co, Sparks, MD). Antibiotics unless otherwise indicated were used at the following concentrations: 100 μg/ml of ampicillin and 10 μg/ml of chloramphenicol for E. coli, 10 μg/ml of erythromycin and 10 μg/ml of chloramphenicol and 1.5 μg/ml of anhydrotetracycline for S. aureus. Human pharyngeal carcinoma cell line (Detroit 562, CCL-138ATCC), and BEAS-2B (normal lung/bronchoalveolar immortalized cell lines, CRL-9609, ATCC), were grown in 24 well plates to obtain a confluent culture. Detroit 562 cell lines were grown in RPMI 1640-GlutaMax-I (GIBCO) tissue culture medium with 10% fetal bovine serum.

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.
