Figure 1. Western blot analysis using the Diagenode monoclonal antibody against the HA protein tag
Western blot was performed on whole cell extracts from HEK293 cells transfected with an HA-tagged expression vector using the Diagenode monoclonal antibody directed against HA (Cat. No. MAb-190-050). The antibody was used at a dilution of 1:1,000. Figure 1 shows the results for untransfected cells, used as a negative control (lane 1) and for cells transfected with a HA-tagged protein (lane 2). The MW marker (in kDa) is shown on the left. A single band is clearly visible in lane 2, but absent in lane 1 showing the high specificity of the HA antibody.
