Biology An Immunofluorescent Method for Characterization of Barrett’s Esophagus Cells Landon J. Inge1, Aaron J. Fowler1, Ross M. Bremner1 1 There is a discernible need for improved information on molecular drivers of Barrett’s Esophagus. Immunofluorescent staining is a useful technique for understanding the effects of cell signaling on cell morphology. We present a simple, effective protocol for the use of immunofluorescent staining to assess therapeutic treatment in Barrett’s Esophagus cells.
