• Target description: 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.

• Physical form: 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.
• Reconstitution: 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.
