Product Overview
This rabbit polyclonal antibody recognizes CCA tRNA nucleotidyltransferase 1, mitochondrial (gene TRNT1) in human samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 50.1 kDa, and the supplier reports an observed band at about 50 kDa.
TRNT1 is the CCA-adding enzyme that builds and repairs the CCA sequence at the 3′ end of tRNAs, the site where amino acids are attached. Working in both the cytosol and mitochondria, it is essential for tRNA maturation, and it also tags unstable tRNAs with a double CCA for degradation, acting in tRNA quality control.

Samples with a confirmed band (WB): human MCF-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 confirmed staining (IHC): human liver cancer tissue, human lung cancer tissue, human rectum adenocarcinoma tissue, human invasive urothelial carcinoma of the bladder 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).
Immunogen
Recombinant human TRNT1 fragment (Met1–Gln410), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places CCA tRNA nucleotidyltransferase 1, mitochondrial in the mitochondrion, cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
