Description générale

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.

Description de la cible

Solute carrier family 12 member 5 (UniProt: Q9H2X9; also known as Electroneutral potassium-chloride cotransporter 2, K-Cl cotransporter 2, Neuronal K-Cl cotransporter, hKCC2, KCC2) is encoded by the SLC12A5 (also known as KCC2, KIAA1176) gene (Gene ID: 57468) in human. KCC2 is a multi-pass homomultimeric membrane protein with seven cytoplasmic domains and twelve transmembrane domains. It can also form heteromultimers with other K+/Cl- cotransporters. Its expression is restricted to neuronal cells. KCC2 mediates electroneutral potassium-chloride cotransport in mature neurons and is required for neuronal Cl- homeostasis. It is the major extruder of intracellular chloride and establishes the low neuronal Cl- levels required for chloride influx after binding of GABA-A and glycine to their receptors, with subsequent hyperpolarization and neuronal inhibition. It is also involved in the regulation of dendritic spine formation and maturation. Overexpression of KCC2 has been reported in colorectal carcinogenesis and bladder urothelial carcinoma. Its tumor promoting effects are reported to be due to its ability to inhibit apoptosis mediated via apoptosis inducing factor-dependent and Endonuclease G-dependent apoptotic signaling pathway. Mutations in SLC12A5 gene are known to cause early infantile epileptic encephalopathy that is characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

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.


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.

Stockage et stabilité

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.
