Staining of proteins with Coomassie Blue, Silver Staining, SYPRO Orange, SYPRO Ruby are demonstrated in this video. Biology Immunoblot Analysis Sean Gallagher1, Deb Chakavarti2 1UVP, LLC, 2Proteomic Center, Keck Graduate Institute of Applied Life Sciences Immunoblotting (western blotting) is a rapid and sensitive assay for the detection and characterization of proteins that works by exploiting the specificity inherent in antigen-antibody recognition. This video provides protocols for protein separation, blotting proteins onto membranes, immunoprobing, and visualization using chromogenic or chemiluminescent substrates. Biology Electrophoretic Separation of Proteins Bulbul Chakavarti1, Deb Chakavarti1 1Proteomic Center, Keck Graduate Institute of Applied Life Sciences In this video, we demonstrate a method for electrophoretic separation of proteins using poly-acrylimide gel electrophoresis (PAGE).
