Eighteen well-characterized phosphorylated or cleaved signaling molecules were simultaneously detected using 50 µg kidney proteins by a slide-based PathScan® Intracellular Signaling Array Kit (#7323, Cell Signaling Technology) according to the manufacturer’s instructions. Images were acquired by briefly exposing the slide to the Chemi Doc XRS+ system (Bio-Rad), and semi-quantitatively analyzed by scanning volume density using Alpha View Software 3.3 (Cell Biosciences, Santa Clara, USA) (33 (link)).
