  • Description
    Rabbit monoclonal [EPR3342] to HB9/HLXB9
  • SpecificityThere 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 notesIs unsuitable for Flow Cyt or ICC.
  • Target

    • FunctionPutative transcription factor involved in pancreas development and function.
    • Tissue specificityExpressed in lymphoid and pancreatic tissues.
    • Involvement in diseaseDefects 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 similaritiesContains 1 homeobox DNA-binding domain.
