Product Overview
This rabbit polyclonal antibody targets F-box only protein 32 (gene FBXO32) in human and mouse samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 41.6 kDa, and the supplier reports an observed band at about 42 kDa.
FBXO32, also called atrogin-1 or MAFbx, is a muscle-enriched F-box protein that serves as the substrate-recognition part of an SCF E3 ubiquitin ligase. It is strongly induced during skeletal muscle atrophy and targets proteins for proteasomal degradation, so it is widely used as a marker in muscle wasting and atrophy research.

Immunogen
Recombinant human FBXO32 fragment (Gln6–Phe355), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places F-box only protein 32 in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Specifically expressed in cardiac and skeletal muscle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
