Example 11
In chamber slides, cells were plated and allowed to adhere overnight in humidified cell culture incubators. The following day, cells were treated with the indicated ligands for 30 min. Subsequently, cells were washed with PBS and fixed with 4% Formaldehyde (Polysciences, Inc.), then blocked and permeabilized with 5% FBS and 0.3% Triton™ X-100 for 1 h. Next, wells were washed and stained with anti-EphA2 antibody, followed by three washes and further incubation with Alexafluor goat anti-mouse 488 secondary antibody (ThermoFisher). Cells were counterstained with DAPI and mounted with Prolong Diamond Antifade (ThermoFisher). Images were acquired with confocal microscope Zeiss 880 Airyscan and processed using Adobe Photoshop CC.
