Target description

Beta-2 adrenergic receptor (UniProt: P07550; also known as Beta-2 adrenoreceptor, Beta-2 adrenoceptor) is encoded by the ADRB2 (also known as ADRB2R, B2AR) gene (Gene ID: 154) in human. β-adrenergic receptors  are activated by the catecholamines (norepinephrine and epinephrine) and are family of the 7-transmembrane superfamily of receptors. Three distinct β adrenergic receptors have been described: β1, β2, and β3. They are identified in cardiac, airway smooth muscle, and adipose tissue, respectively and display about 65% to 70% homology. β2-adrenergic receptor is a multi-pass membrane glycoprotein with four extracellular domains, seven transmembrane domains, and four cytoplasmic domains. It mediates the catecholamine-induced activation of adenylate cyclase  that results in the production of cyclic AMP and subsequent activation of protein kinase A (PKA). Most of the downstream effects of β-adrenergic receptor activation are due to the action of PKA. Activation of β2 receptor causes smooth muscle relaxation, peripheral vasodilation, and subsequent hypotension.  It is palmitoylated at cysteine 341, which reduces accessibility of phosphorylation sites by anchoring the receptor to the plasma membrane. Agonist stimulation of β-adrenergic receptors promote de-palmitoylation and allows phosphorylation of serine 345 and 346. Phosphorylation of β2 receptor by PKA and β-adrenergic receptor kinase (BARK) mediates homologous desensitization of the receptor. PKA-mediated phosphorylation appears to facilitate phosphorylation by BARK. 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, 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.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
