Our Abpromise guarantee covers the use of ab58920 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 a concentration of 2.5 µg/ml. Detects a band of approximately 29 kDa (predicted molecular weight: 35 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.



  • Lane 1 : Anti-Follistatin antibody (ab58920) at 1 µg/ml
    Lane 2 : Anti-Follistatin antibody (ab58920) at 2.5 µg/ml
    Lane 3 : Anti-Follistatin antibody (ab58920) at 5 µg/ml

    All lanes : Cell lysate prepared from human Jurkat cells

    Lysates/proteins at 25 µg per lane.

    Predicted band size: 35 kDa

Thank you for your message and for providing this further information.

I can confirm, as previously discussed, that the recommended concentration for Western blot using this antibody is 2.5 µg/ml (1:400) as stated on the datasheet. This is a recommendation only and may require some optimization.

I am sorry to hear the suggestions made have not improved the results on this occasion. I appreciate the time you have spent on these experiments and would be pleased to arrange a free of charge replacement or credit note in compensation.

I look forward to hearing from you with details of how you would like to proceed.

Sorry for the misunderstanding. Both antibodies have been developed to recognise specifically the follistatin. I would say that both products are equally specific to the target. The polyclonal antibody was raised against a 49 amino acid long peptide. The bulk of polyclonal antibodies would therefore bind at different places along this peptide. On the other hand, the monoclonal would bind to one particular fragment of the protein. Unfortunately the epitope for ab89515 has not been mapped. It can be anywhere along the follistatin since the immunogen used is the full length Human protein. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
