Our Abpromise guarantee covers the use of ab21288 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
ICC/IF Use at an assay dependent concentration. PubMed: 21163940
IP Use at an assay dependent concentration. PubMed: 21163940
IHC-P Use a concentration of 2 µg/ml.
WB Use a concentration of 0.5 - 1 µg/ml. Detects a band of approximately 42 kDa (predicted molecular weight: 49 kDa).


  • Function
    Adapter protein of the Toll-like and IL-1 receptor signaling pathway that is involved in the activation of NF-kappa-B via MAP3K1. Promotes proteolytic activation of MAP3K1. Involved in the BMP signaling pathway. Required for normal embryonic development (By similarity). Required for efficient assembly of mitochondrial NADH:ubiquinone oxidoreductase.
  • Sequence similarities
    Belongs to the ECSIT family.
  • Cellular localization
    Cytoplasm. Nucleus. Mitochondrion.

Thank you for your enquiry and your interest.

I regret to inform you that the immunogen sequence is commercially sensitive information and we are not allowed to release it. However, it is between residues 301 and 350 aa accession number NP_05...

Thank you very much for your reply and Nezira's. At this stage I think it would be worth looking at Nezira's protocol in detail in light of the fact that the first lot did not give her the results expected. Can you please ask Nezira to click on th...

Thank you again for your enquiry. I spoke to a colleague of mine who also agreed that you may be detecting the endogenous protein. Did you cleave the tags? The tags may be adding the additional kDa’s to your bands. Another possibility is that differ...
