Product Overview
This rabbit polyclonal antibody targets DNA polymerase iota (gene POLI) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 83.0 kDa, and the supplier reports an observed band at about 83 kDa.
DNA polymerase ι (POLI) is a Y-family translesion polymerase that can insert nucleotides opposite certain damaged bases when replication stalls. It is error-prone and shows unusual template preferences, often misinserting G opposite T. It is studied in DNA damage tolerance, mutagenesis and immunoglobulin hypermutation.

|---|
Samples with a confirmed band (WB): human HeLa cells, human placenta tissue, human A549 cells, human SK-OV-3 cells, rat testis tissue, rat kidney tissue, rat stomach tissue, mouse testis tissue, mouse kidney tissue, mouse stomach 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, 50 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 1:10000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human DNA Polymerase iota. Sequence identity with the mouse and rat orthologs: 70.6% and 76.5%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places DNA polymerase iota in the nucleus. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
