Example 201

Materials and Methods:

Cells

The human hepatoblastoma cell line HepG2 (HB-8065, ATCC, Manassas, Va., USA) was cultured in DMEM-Glutamax™ (5.5 mM glucose) supplemented with 10% foetal bovine serum, streptomycin (100 μg/ml) and penicillin (100 units/ml) at 37° C. in 5% CO2. For viability assays, cells were seeded in white 96-well Nunclon plates at a density of 20,000 cells/well and left overnight to adhere before experiments were conducted.

Cell Viability Assay

Zn chelators dissolved in DMSO were added to white 96-well plates containing 20000 HepG2 cells/well at concentrations ranging from 1 to 1×10−6 mM (max DMSO concentration never exceeded 1%) and incubated for 24 hours at 37° C. After 24 hours, AlamarBlue® cell viability reagent (Thermo Fisher, Carlsbad, USA) was added (10% final concentration) and incubated for 4 hours at 37° C. This dye is a red-ox indicator yielding a fluorescent signal proportional to viable cells in each well that was measured in a fluorescence plate reader at ex550 nm/em603 nm (Clariostar, BMGlabtech, Germany) (O'Brien et al., 2000). Data from 8 replicates were fitted by non-linear regression to estimate IC50 values using GraphPad Prism (GraphPad Software Inc, USA).

Producing and Inactivating HRV16 Stocks

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human rhinovirus 16 (HRV16) (VR-283, strain 11757, lot 62342987) was purchased from the ATCC and stocks were produced by infecting HeLa Ohio cells in virus medium (DMEM GlutaMax containing 25 mM D-glucose supplemented with 10% FCS and 2 mM l-glutamine) as described previously (Bennett et al, 2012 (link)). Briefly, HeLa Ohio cells were grown to 80% confluence at 37 °C and infected with 5 ml HRV16 or control media for 1 h at room temperature with agitation. The remaining solution was made to 10 ml and the cells with HRV16 left for 48 h at 37 °C to allow for 90% cytopathic effect to develop. Supernatants were then clarified by centrifugation and filtration (Bennett et al, 2012 (link)) and 1 ml stocks were produced and stored at −80 °C. To UV inactivate HRV16 it was treated with UV light (1000 mJ/cm2) for 20 min. Inactivation was confirmed by adding the inactivated virus to HeLa Ohio cells and checking for cytopathic effect.

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.
