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

Parvalbumin alpha (UniProt: P20472; also known as PV) is encoded by the PVALB gene (Gene ID: 5816) in human. Parvalbumin is a low molecular weight soluble protein that binds two calcium ions with high affinity and is implicated in intracellular calcium regulation and trafficking. It is composed almost entirely of two EF-hand domains (aa. 39-74 & 78-110) and is structurally related to calmodulin and troponin C. It serves as a slow Ca2+ buffer that affects the amplitude and time course of intracellular Ca2+ transients in terminals after an action potential, and hence may regulate short-term synaptic plasticity. During nervous system development, its expression is shown to accompany the maturation of functional circuits. Parvalbumin containing neurons are abundant in the cortex, the hippocampus, and the thalamus. It is present in GABAergic interneurons in the nervous system, especially the reticular thalamus. Parvalbumin interneurons are a subset of inhibitory GABAergic neurons that control the excitability of post-synaptic pyramidal neurons. Dysfunction or loss of parvalbumin interneurons has been implicated in cognitive deficits associated with several well-known psychiatric disorders, including schizophrenia and depression. 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. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


30 μg/mL after reconstitution at 25 μL. 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.
