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.

Target description

Gamma-aminobutyric acid receptor subunit a1 (UniProt: P14867; also known as GABA(A) receptor subunit alpha-1) is encoded by the GABRA1 gene (Gene ID: 2554) in human. GABA is the major inhibitory neurotransmitter in the central nervous system that inhibits the generation of the action potential of the neuron. It plays an important role in the formation of functional inhibitory GABAergic synapses in addition to mediating synaptic inhibition as a GABA-gated ion channel. It is involved in the pathogenesis of certain neurological and psychiatric disorders. GABA interacts with the GABAA and GABAB receptors, which are widely distributed throughout the nervous system and in a variety of cell types. On binding of two GABA molecules to the extracellular receptor domain, a conformational change is induced in the oligomer and Cl moves into the cell leading to an inhibitory hyperpolarization. GABAA and GABAB receptors differ in their pharmacological, electrophysiological, and biochemical properties. GABA a1 receptor subunit is part of the heteropentamer formed by a combination of a1, b2, and y2 subunits. GABA A receptor a1 subunit is synthesized with a signal peptide (aa 1-29) which is subsequently cleaved off to generate the mature form that contains four transmembrane domains (aa 252-273; 279-300; 313-334; and 422-443), one extracellular domain (aa 28-251), and a cytoplasmic domain (aa 335-421). This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
