Product Overview
This rabbit polyclonal antibody detects ribonucleoside-diphosphate reductase large subunit (gene RRM1) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 90.1 kDa, and the supplier reports an observed band at about 90 kDa.
RRM1 is the large catalytic subunit of ribonucleotide reductase, the enzyme that converts ribonucleotides into the deoxyribonucleotides needed for DNA synthesis and repair. It carries the active site and allosteric sites that balance dNTP pools, and it is a direct target of the nucleoside analog gemcitabine.

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): U87 cells.
Immunogen
Recombinant human RRM1 fragment (Asp129–Gln730), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ribonucleoside-diphosphate reductase large subunit in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
