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

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 190 kDa (predicted molecular weight: 122 kDa).
Flow Cyt 1/200 - 1/1000.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • Application notes
    Is unsuitable for ICC,IHC-P or IP.
  • Target

    • Function

      Receptor that binds both PDGFA and PDGFB and has a tyrosine-protein kinase activity.
    • Tissue specificity

      Expressed in primary and metastatic colon tumors and in normal colon tissue. Tumors may express a different isoform to that found in normal tissue.
    • Involvement in disease

      Note=A chromosomal aberration involving PDGFRA is found in some cases of hypereosinophilic syndrome. Interstitial chromosomal deletion del(4)(q12q12) causes the fusion of FIP1L1 and PDGFRA (FIP1L1-PDGFRA).
    • Sequence similarities

      Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
      Contains 5 Ig-like C2-type (immunoglobulin-like) domains.
      Contains 1 protein kinase domain.

    Thank you for your reply. I apologize for the confusion, I thought you were saying that 45 minutes was the exposure time for the film. I am not an expert in PDGF do I do not know what prolonged stimulation with PDGF would do. I would recommend using a higher percent gel, since your expected band should be pretty close to the top, but I think that bright band you are seeing is not your true target band but rather an artifact where maybe some of the sample has aggregated. I would also block for 2 hours at room temperature and then incubate overnight at 4 degrees with the primary, rather than the other way around. Please let me know if these suggestions do not improve your result.
