Following exposure to 1 µmol L−1 BK, NT or SP for 60 minutes, the cells were quickly washed with ice-cold phosphate-buffered saline (PBS), fixed with 4% paraformaldehyde (Electron Microscopy Sciences, Fisher Scientific, Waltham, MA, USA) for 5 minutes and blocked for 30 minutes (10% goat serum and 0.2% Triton-X100 in PBS). Then, the BMEC monolayers were incubated with mouse-anti human claudin-5 (dilution 1:100, ThermoFisher; RRID: AB_2533200) or mouse-anti human occludin (dilution 1:100, ThermoFisher; AB_2533101) antibodies overnight at 4°C. Primary antibodies were detected using a goat-anti mouse IgG Alexa Fluor® 555-conjugated secondary anti-body (ThermoFisher). In experiments involving F-actin, freshly fixed BMEC monolayers were stained with 0.1 mg mL−1 fluorescein isothiocyanate-conjugated phalloidin (Sigma-Aldrich) for 30 minutes. All images were acquired using a DMi8 inverted epifluorescence microscope (Leica Microsystems, Wetzlar, Germany). Images were analysed using IMAGEJ (NIH, Bethesda, MD, USA).

Cells were quickly washed with ice-cold PBS and xed with 100% cold methanol or 4% paraformaldehyde, followed by blocking in PBSG (PBS with 10% normal goat serum (ThermoFisher)) with 0.2% Triton-X100 (Sigma-Aldrich) for 1h at room temperature. Cells were incubated in presence of primary antibodies targeting GLUT-1 (SPM498 clone, RRID:AB_10979643, 1:100; ThermoFisher), GLUT-3 (RRID:AB_10694437, 1:100;; ThermoFisher), GLUT4 (RRID:AB_11153908, 1:100; ThermoFisher), occludin (RRID: AB_2533101, 1:100, ThermoFisher), and claudin-5 (AB_2533200, 1:100, ThermoFisher) overnight at 4°C, followed by detection using Alexa-Fluor-conjugated secondary antibodies (ThermoFisher) for 1h at room temperature. Cells were observed using Leica DMI8 inverted epi uorescence microscope (Leica Microsystems, Buffalo Grove, IL, USA). Micrograph images were processed and analyzed using ImageJ (NIH, Bethesda, MD, USA).
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.
