General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Clone 1M8 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects RAD51 protein.


His-tagged full-length recombinant human RAD51 protein.


Anti-RAD51, clone 1M8 ZooMAb, Cat. No. ZRB1492, is a recombinant Rabbit monoclonal antibody that specifically targets RAD51 and is tested in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected RAD51 in HeLa and NIH3T3 cell lysates.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected RAD51 in human testis tissue sections.

Affinity Binding Assay Analysis: 100 μg/mL from a representative lot detected RAD51 in RAD51 and GST protein showed a KD of 1.0 x 10^-12 whereas binding of ZRB1492 to non-specific GST protein showed a KD of 1.7 x 10^-3.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected RAD51 in HeLa, A431, HepG2, and NIH 3T3 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Target description

Nuclear factor erythroid 2-related factor 2 (UniProt: Q16236; also known as NF-E2-related factor 2, NFE2-related factor 2, Nrf-2, HEBP1, Nuclear factor, erythroid derived 2, like 2) is encoded by the NFE2L2 (also known as NRF2) gene (Gene ID: 4780) in human. Nrf2 is a cap n collar basic-region leucine zipper transcription factor that that heterodimerizes with small Maf proteins. It is involved in adaptation of cells to oxidative stress and electrophiles. It binds to antioxidant response (ARE) elements in the promoter regions of target genes and induces a set of cytoprotective genes that are involved in the synthesis of reduced glutathione (GSH), repair of oxidized protein thiols, scavenging of reactive oxygen species, and drug metabolism. It is cytosolic under unstressed conditions, but translocates into the nucleus upon induction by electrophilic agents. Under normal unstressed conditions it is rapidly turned over in a Keap-1 dependent manner through Cul3-Rbx1 ubiquitination and proteasomal degradation. Phosphorylation of Ser40 by protein kinase C in response to oxidative stress dissociates Nrf2 from its Keap-1 and promotes its translocation into the nucleus. It is widely expressed with highest expression in liver, skeletal muscle, luminal cells of the stomach and intestine, lining of the bronchi and alveoli, and in renal tubules; followed by heart, spleen, testis and brain. Nrf2 is constitutively upregulated in many tumors due to somatic mutations in the Keap1 or Nrf2 genes. Tumors over-expressing Nrf2 exhibit increased resistance to chemotherapeutic drugs and higher rates of proliferation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
