Figure 2. Western blot analysis using the Diagenode monoclonal antibody against the His protein tag
Western blot was performed on whole cell extracts from HEK293 cells transfected with a His-tagged expression vector using the Diagenode monoclonal antibody directed against His (Cat. No. MAb-191-050). The antibody was used at a dilution of 1:1,000. Figure 2 shows the results for cells transfected with a HA-tagged protein (lane 1) and for untransfected cells, used as a negative control (lane 2). The MW marker (in kDa) is shown on the left. A single band is clearly visible in lane 1, but absent in lane 2 showing the high specificity of the His antibody.
