This video showcases a monocyte monolayer assay utilizing primary monocytes from peripheral blood to assess Fcγ receptor-mediated phagocytosis with poly D antibody-opsonized R2R2 red blood cells.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Peripheral Blood Mononuclear Cell Isolation Obtain human whole blood from a healthy donor or a patient via venipuncture using vacutainers containing acid-citrate-dextrose (ACD) anticoagulant (yellow-top tubes). NOTE: Whole blood can be stored in ACD at room temperature (18-22 °C) for up to 36 hours be…
