General description

KCC2 is a member of the cation-chloride cotransporter gene family. It acts as a K-Cl cotransporters. KCCs normally lower intracellular chloride concentrations below the electrochemical equilibrium potential and depending on the chemical concentration gradients of potassium and chloride, KCC2 can operate as a net efflux or influx pathway. It is proposed to act as the main chloride extruder to promote fast hyperpolarizing postsynaptic inhibition in the brain. KCC2 is expressed at high levels in neurons throughout the nervous system and immunofluorescence shows that the protein is localized at inhibitory synapses of the spinal cord. Studies in mice have shown that KCC2 reduces GABA′s inhibitory signaling, resulting in motor defects, epilepsy, and anxiety-like behavior.


N-terminal His-tag fusion protein corresponding to residues 932-1043 of rat K+/Cl- Cotransporter (KCC2).


Recognizes rat K+/Cl- Cotransporter (KCC2), Mr ~140 kDa. An unknown band >200 kDa was also detected.

Physical form

Protein A Purfied

Purified rabbit polyclonal IgG in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide and 30% glycerol. Liquid at -20°C.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
For maximum recovery of product, centrifuge the vial prior to removing the cap.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
