Mouse IgG1 [CT6] - Isotype control (ab81216)


  • Product nameMouse IgG1 [CT6] - Isotype control
    See all Mouse isotype controls
  • SpecificityThe antibody reacts with a Guinea pig lymphocyte subset probably analog to human CD8 (cytotoxic/suppressor) subset. Although this monoclonal originally was developed for the detection of a Guinea pig lymphocyte subset, it also can be used as a negative control for the mouse IgG1 subclass. It is sufficient for 100 tests. The antibody does not react with the 170-180 kD glycoprotein which is strongly correlated with the degree of Multi Drug Resistance. The antibody is sufficient for 100 tests.
