Target description

Retinoic acid receptor alpha (UniProt: P10276; also known as RAR-alpha, Nuclear receptor subfamily 1 group B member 1) is encoded by the RARA (also known as NR1B1) gene (Gene ID: 5914) in human. RAR-alpha is a nuclear receptor of the steroid/thyroid superfamily of nuclear receptor proteins that regulate gene expression by binding to RNA and other elements of DNA response. RAR-alpha forms heterodimer with RXR (via C-terminus) and this association is enhanced by pulsatile shear stress. The RAR-alpha/RXR heterodimer bind to the retinoic acid response elements composed of tandem 5′-AGGTCA-3′ sites known as DR1-DR5. Its nuclear localization depends on ligand binding, phosphorylation, and sumoylation. Phosphorylation on serine 77 is shown to be crucial for its transcriptional activity. Phosphorylation by Akt1 is required for the repressor activity but it has no effect on DNA binding, protein stability, or subcellular localization. In the absence of ligand, the heterodimer associates with a multiprotein complex containing transcription corepressors that induces histone deacetylation, chromatin condensation and transcriptional suppression. Upon ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. RAR-alpha has two NR C-4 type of zinc-finger domains (aa 88-108 and 124-148). This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
