The cultured N2a cells fixed in 4 % paraformaldehyde were thoroughly rinsed with PBS three times and treated with 10 % Triton X-100 for 10 min to rupture the cell membranes. The fixed cells were then blocked with 10 % donkey serum. One hour later, the coverslips were incubated overnight at 4 °C with the following primary antibodies: anti-HA (sc-7392, 1:200, Santa Cruz Biotechnology) or anti-annexin A1 (sc-12740, 1:200, Santa Cruz Biotechnology). After washing three times, the fixed coverslips were incubated with Alexa Fluor 488-conjugated AffiniPure goat anti-mouse IgG (H+L) (Jackson Immuno Research, West Grove, PA) for 60 min at room temperature. Finally, the fluorescence was captured by fluorescence microscopy (IX73, Olympus). Regional fluorescence intensities were quantified using Image Pro Plus software. To measure regional intensities, small circles within the cytoplasmic or nuclear regions of each cell were selected using the elliptical marquee tool. The intensity within each circle was obtained using the histogram function for each color channel, which was selected using the layers/channels palette. The values were recorded, for evaluation of the ratio of the nuclear to cytoplasmic intensity; we examined up to 10 independent fields of cells and scored at least 100 cells for each measurement.

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.
