Immunoblot Analysis of DENV Infection

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunoblot assays were performed as previously described (Marceau et al., 2016 (link)). HEK293 cells were infected with DENV (MOI=0.5) and treated with different concentrations of NGI-1 for 52h. As control, cells were treated with 10μg/ml tunicamycin for 4h before harvest. To detect DENV proteins, anti-prM (Genetex GTX128092) at a dilution of 1:1000, anti-E (Genetex GTX127277) at a dilution of 1:2000, and anti-NS1 (Genetex GTX630556) at a dilution of 1:2000 were used. As loading control anti-p84 (Genetex GTX70220) at a dilution of 1:5000 was used.

Evaluating Furin Expression in Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Furin expression in cells was evaluated by Western blotting. Briefly, monolayers of Vero and Vero-furin cells were lysed in 1% Triton, 100 mM Tris, 2 M NaCl, and 100 mM EDTA; lysates were then clarified by centrifugation at 3,500 x g. Recombinant human furin (R&D Systems) was loaded in gels as a reference. Furin was detected using primate and human furin-reactive antibody (ThermoFisher) at 2 ug/ml. prM and E proteins in partially purified virus preparations were detected using monoclonal antibodies (mAbs) GTX128092 (Genetex) and, 4G2 respectively, at 1 μg/ml.

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.
