  • Description

    Rabbit monoclonal [EPR3342] to HB9/HLXB9/MNX1
  • Host species

  • Specificity

    There have been conflicting results with this antibody in IHC-P. PMID 21484430 reported specific labeling in IHC-P, but internally we were unable to reproduce these results. Thus, we have removed IHC-P as a guaranteed application, and we welcome any further feedback from customers using this antibody in IHC-P.

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 48 kDa (predicted molecular weight: 41 kDa).
IP 1/50.
  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • Target

    • Function

      Putative transcription factor involved in pancreas development and function.
    • Tissue specificity

      Expressed in lymphoid and pancreatic tissues.
    • Involvement in disease

      Defects in MNX1 are a cause of Currarino syndrome (CURRAS) [MIM:176450]. The triad of a presacral tumor, sacral agenesis and anorectal malformation constitutes the Currarino syndrome which is caused by dorsal-ventral patterning defects during embryonic development. The syndrome occurs in the majority of patients as an autosomal dominant trait.
    • Sequence similarities

      Contains 1 homeobox DNA-binding domain.
    • Cellular localization

    Customer reviews and Q&As


    I will send the IHC protocol for ab59795 when I receive it, hoepfully in the next day or two. As I mentioned, Abcam does not validate this antibody for IHC in-house. We do not have free samples of any of our antibodies, but ab59795 is covered by our Abpromise guarantee for this application (IHC on paraffin-embedded tissue sections) and this species (human). If I cannot help you obtain a satisfactory result, I will be happy to look into replacing this. However, I am concerned about the possility that this transcription factor is not present in prostate. Do you have any other tissues you can include as apositive control, in particular pancreas?
