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

Glutamate receptor 1 (UniProt: P42261; also known as GluR-1, AMPA-selective glutamate receptor 1, GluR-A, GluR-K1, Glutamate receptor ionotropic-AMPA 1, GluA1) is encoded by the GRIA1 (also known as GLUH1, GLUR1) gene (Gene ID: 2890) in human. Four different AMPA receptors have been described and are designated as GluR1, GluR2, GluR3, and GluR4. These receptors mediate fast excitatory neurotransmission in the brain and are involved in multiple brain functions, including cognition, movement, learning, and memory. Each of the AMPA receptor subunit can exist in either ′flip′ or ′flop′ form and the efficacy of glutamate is believed to be higher at the ′flip′ form. These receptors contain four sites where an agonist can bind. The binding site is formed by the N-terminal tail and the extracellular loop between transmembrane domains three and four. Upon agonist binding, these two loops move towards each other, which opens the pore. GluR-1 is a multi-pass membrane protein that is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off. It is widely expressed throughout the nervous system and can exist in homotetrameric or heterotetrameric form. Tetramers may be formed by the dimerization of dimers. GluR-1 has several phosphorylation sites on the intracellular carboxy terminus. Many of these sites play a role in receptor regulation and synaptic plasticity. Reversible phosphorylation a of GluR-1 at serine 831 and 845 is shown to play a critical role in bidirectional synaptic plasticity. Both these phosphorylations are important in long-term potentiation and long-term depression. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
