Product Overview
This rabbit polyclonal antibody targets tRNA (gene NSUN3) in human and monkey samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 38.2 kDa, and the supplier reports an observed band at about 38 kDa.
NSUN3 is a mitochondrial methyltransferase that places 5-methylcytosine at the anticodon wobble position of mitochondrial tRNA-Met. This is further oxidized to 5-formylcytosine, which allows the tRNA to read both AUA and AUG codons during mitochondrial translation. NSUN3 is studied in mitochondrial gene expression and disease.

Samples with a confirmed band (WB): human placenta tissue, monkey COS-7 cells.
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 a confirmed signal (flow cytometry): U251 cells.
Immunogen
Recombinant human NSUN3 fragment (Lys12–Glu310), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and monkey. UniProt places tRNA 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).
