Product Overview
This rabbit polyclonal antibody recognizes trifunctional enzyme subunit beta, mitochondrial (gene HADHB) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 51.3 kDa, and the supplier reports an observed band at about 45 kDa.
Trifunctional enzyme subunit beta (HADHB) is part of the mitochondrial trifunctional protein, which carries out the last three steps of long-chain fatty acid β-oxidation. The beta subunit supplies the 3-ketoacyl-CoA thiolase activity that releases acetyl-CoA each cycle. Mutations in HADHB cause trifunctional protein deficiency, and it is studied in mitochondrial energy metabolism.

Immunogen
Recombinant human HADHB fragment (Ala18–His379), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 91.2% and 85.9%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places trifunctional enzyme subunit beta, mitochondrial in the mitochondrion, mitochondrion inner membrane, mitochondrion outer membrane and endoplasmic reticulum. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
