Mouse monoclonal antibodies for anti-6X his-tag (Abcam - ab18184) (1:1,000), HA (Biolegend 901501) (1:1,000), α-tubulin (Clone 12G10 from Developmental Studies Hybridoma Bank, University of Iowa) (1:5,000) and viral envelope (Merck-Millipore MAB10216) (1:1,000) were used. Rabbit polyclonal antibodies for GAPDH (1:5,000) were from Cell Signaling Technology (CST 2118). Rabbit polyclonal dengue-capsid antibody was used for immunoblotting (1:1,000) (Agrawal et al., 2013 (link)). Rabbit polyclonal DDX3X (R648) antibody (1:2,000 for western blotting and 1:1,000 for immunofluorescence) has been described before (Angus et al., 2010 (link)). Anti-rabbit (Merck-Millipore) or anti-mouse (Sigma) IgG secondary antibodies raised in goat and conjugated with horseradish peroxidase (HRP) (1:2,000) were used. HRP-conjugated secondary antibodies specific to IgG-light chain (Jackson's Immunoresearch Lab) were used (1:10,000) for probing blots of immunoprecipitation.

The neurons were lysed with lysis buffer (Beyotime, Nantong, China), and the proteins were separated by 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and then transferred onto polyvinylidene difluoride membranes. The membranes were blocked in 5% nonfat milk at room temperature for 1 hour, and thereafter incubated with primary antibodies [anti-GPX4 (1:5000; ab125066, rabbit, Abcam), anti-xCT (1:1000; ab175186, rabbit, Abcam), anti-β-actin (1:5000; sc47778, mouse, Santa Cruz Biotechnology, Santa Cruz, CA, USA) and anti-GAPDH (1:2000; CST2118, rabbit, Cell Signaling Technology, Boston, MA, USA)] overnight. GPX4 and xCT are both key ferroptosis markers. The blots were then incubated with secondary antibodies (horseradish peroxidase-linked anti-mouse IgG (CST7076, 1:3000; Cell Signaling Technology) and horseradish peroxidase-linked anti-rabbit IgG (CST7074, 1:3000; Cell Signaling Technology) at room temperature for 1 hour. Finally, the blots were visualized using an enhanced chemiluminescence system (ChemiDox XRS; Bio-Rad, Hercules, CA, USA). All grayscale values were normalized to that of β-actin or GAPDH using ImageJ software (National Institutes of Health).

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.
