Product Overview
This rabbit polyclonal antibody targets NADP-dependent malic enzyme (gene ME1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 64.2 kDa, and the supplier reports an observed band at about 64 kDa.
ME1 is the cytosolic NADP-dependent malic enzyme, which converts malate to pyruvate and CO2 while generating NADPH. This NADPH supports fatty acid synthesis and antioxidant defenses. ME1 is expressed strongly in lipogenic tissues such as liver and fat and is studied in lipid metabolism and cancer metabolism.

Immunogen
Recombinant human ME1 fragment (Met1–Gln572), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places NADP-dependent malic enzyme in the cytoplasm. Tissue expression noted by UniProt (human): Expressed in all tissues tested including liver, placenta and white adipose tissue. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
