Description

Ribonucleotide reductase M1 (RRM1) serves as the catalytic subunit of ribonucleotide reductase, the enzyme responsible for converting ribonucleotides to deoxyribonucleotides—a rate-limiting step essential for DNA synthesis and repair. This fundamental role in nucleotide metabolism positions RRM1 as a significant marker in cancer research, particularly in studies examining tumor proliferation, chemotherapy resistance mechanisms, and therapeutic response prediction.

This recombinant monoclonal antibody, clone 7D10, offers researchers the consistency and reliability that comes with sequence-defined production. Unlike traditional hybridoma-derived antibodies, recombinant technology ensures lot-to-lot reproducibility, giving you confidence that your experimental results will remain comparable across extended studies and collaborative projects.

Validation across multiple experimental platforms demonstrates this antibody's versatility in your workflow. Western blot analysis confirms specific detection at the expected 90 kDa molecular weight across a diverse panel of human cell lines including PC-3, K562, A549, SW620, HEK293, HepG2, and HeLa cells, as well as mouse NIH/3T3 cells, supporting the documented cross-species reactivity with human and mouse samples. Immunohistochemistry staining has been validated in paraffin-embedded human colorectal cancer tissue, revealing clear localization patterns relevant to oncology research. Flow cytometry analysis in HeLa cells demonstrates robust signal separation from isotype controls, enabling quantitative assessment of RRM1 expression at the single-cell level.

Whether you are investigating nucleotide metabolism, exploring mechanisms of drug resistance in cancer models, or characterizing RRM1 expression patterns across tissue types, this antibody provides a dependable tool backed by comprehensive validation data across your key applications.
