Anti-ALDH2 antibody [EPR4493] (ab108306)


  • Product name
    Anti-ALDH2 antibody [EPR4493]
    See all ALDH2 primary antibodies
  • Description
    Rabbit monoclonal [EPR4493] to ALDH2
  • Specificity
    The antibody immunogen has 82% homology with ALDH1B1 (P30837) and 77% with ALDH1A1 (P00352). BLAST results show for both proteins 6 aa in a row with 100% homology, therefore a cross-reactivity with these proteins is likely.
  • Tested applications
