Anti-CRFR1/CRHR1 Antibody, clone 1N21 ZooMAb^® Rabbit Monoclonal

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

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.

Clone 1N21 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Corticotropin-releasing factor receptor 1 (CRFR1). It targets an epitope within 15 amino acids from the first extracellular domain within the N-terminal half.

Corticotropin-releasing factor receptor 1 (UniProt: P34998; also known as CRF-R-1, CRF-R1, CRFR-1, Corticotropin-releasing hormone receptor 1, CRH-R-1, CRH-R1) is encoded by the CRHR1 (also known as CRFR, CRFR1, CRHR) gene (Gene ID: 1394) in human. CRFR1, a member of the G-protein coupled receptor 2 family, is a multi-pass, heterodimeric, membrane glycoprotein, which is synthesized with a signal peptide (aa 1-23) that is subsequently cleaved off to produce the mature protein that contains seven transmembrane domains. It is predominantly expressed in the cerebellum, pituitary, cerebral cortex, and olfactory lobes. It can heterodimerize with G protein-coupled estrogen receptor 1 (GPER1). CRFR1 is reported to bind neuropeptides of the corticotropin releasing hormone family that are major regulators of the hypothalamic-pituitary-adrenal pathway and plays an important role in orchestrating neuroendocrine, behavioral, and autonomic responses to stress. It displays high affinity for corticotropin-releasing factor(CRH) and urocortin (UCN). Ligand binding is shown to result in a conformation change, which triggers signaling via G proteins and down-stream effectors, such as adenylate cyclase. CRFR1 is also required for normal embryonic development of the adrenal gland and for normal hormonal responses to stress. Phosphorylation of serine 301 that is located in the third intracellular loop is shown to be critical for its efficient coupling to G proteins and to second messenger generation. Its phosphorylation at serine 330 by protein kinase A (PKA) prevents maximal coupling to Gq-protein, and thereby negatively regulates its downstream signaling. Five isoforms of CRH-R1 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

KLH-conjugated linear peptide corresponding to 15 amino acids from the first extracellular domain within the N-terminal half of human Corticotropin-releasing factor receptor 1 (CRFR1).

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
