Product Overview
This rabbit polyclonal antibody detects elongation factor Tu, mitochondrial (gene TUFM) in human, mouse and rat samples and is validated for Western blot, ICC/IF and ELISA. The predicted molecular weight is 49.5 kDa, and the supplier reports an observed band at about 50 kDa.
TUFM is mitochondrial elongation factor Tu, a GTPase that brings aminoacyl-tRNAs to the A site of mitochondrial ribosomes during protein synthesis. It is recycled by TSFM, and beyond translation it has been reported to regulate autophagy and to dampen RIG-I–MAVS antiviral signaling.

Immunogen
Recombinant human TUFM fragment (Arg8–Arg271), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places elongation factor Tu, mitochondrial in the mitochondrion matrix. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
