Our Abpromise guarantee covers the use of ab9741 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration. To detect mGM-CSF by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant mGM-CSF is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
ELISA Use at an assay dependent concentration. To detect mGM-CSF by direct ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant mGM-CSF.
Neutralising Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of mGM-CSF (0.6 ng/ml), a concentration of 0.012 - 0.02 µg/ml of this antibody is required.
IHC-P Use a concentration of 5 µg/ml.

  • Performed under reducing conditions.

    Observed band size: 17 kDa (why is the actual band size different from the predicted?)

    Western blot analysis of recombinant GM-CSF using ab9741 at 0.1μg/ml. Bottom band - dye front.

  • Performed under non-reducing conditions.

    Observed band size: 17 kDa (why is the actual band size different from the predicted?)

    Western blot analysis of recombinant GM-CSF using ab9741 at 0.1μg/ml. Bottom band - dye front.

  • Less than 0.10 ug/ml ab9741 will neutralize 50% of the bioactivity of 1 ng/ml m-GM-CSF.
  • IHC image of GM-CSF staining in Human normal tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab9741, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you very much for your inquiry.

The immunogen of ab9741 was the whole GM-CSFprotein of mouse. Mouse GM-CSF only shows 71% homology with rat as a whole protein and therefore I cannot recommend to use this antibody for rat samples.

Thank you for contacting us with your question.
The GM-CSF protein is expected to run around 16 kDa, however there are 4 known glycosylation sites, each adding around 2 kDa to the protein, so the protein generally runs around 24 kDa on a Western b...

Unfortunately, we only test against the recombinant murine GM-CSF and do not test tissue samples. In the naturally occurring GM-CSF there are potential glycolisation sites which could cause the protein to migrate higher on a WB. Sorry we coul...
