Product Overview
This rabbit polyclonal antibody recognizes threonine--tRNA ligase, mitochondrial (gene TARS2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 81.0 kDa, and the supplier reports an observed band at about 72 kDa.
TARS2 is the mitochondrial threonyl-tRNA synthetase. It attaches threonine to mitochondrial tRNA(Thr) in an ATP-dependent reaction and corrects mischarged tRNAs through an editing domain, supporting translation of mitochondrially encoded proteins; mutations cause a rare mitochondrial disorder.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human HeLa cells, human THP-1 cells, human Raji cells, rat liver tissue, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colonic adenocarcinoma tissue, human lung cancer tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): T-47D cells.
Samples with a confirmed signal (flow cytometry): SiHa cells.
Immunogen
Recombinant human TARS2 fragment (Gln69–Phe718), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places threonine--tRNA ligase, mitochondrial in the mitochondrion matrix. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
