A549 cells were infected with WT WSN or WSN-NS1-R38A-K41A mutant virus at a multiplicity of infection (MOI) of three. At the indicated time points post-infection, cells were fixed with 4% paraformaldehyde in PBS and permeabilized with 0.1% Triton X-100 in PBS. Mouse anti-UAP56 antibody (LS-C172345; LSBio) and rabbit anti-NS1 antibody (PA5-32243; Thermo Fisher) were used as primary antibodies. Alexa 488-conjugated anti-rabbit and Alexa 594-conjugated anti-mouse antibodies (Life Technologies) were used as secondary antibodies. Slides were mounted in mounting media with DAPI, and analyzed by using LSM510 META (Carl Zeiss). The immunofluorescence co-localization of NS1 and UAP56 was assessed by Pearson’s correlation coefficient of red- and green-pixels, calculated by using the FIJI “coloc2” function1 (Schindelin et al., 2012 (link)).

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.
