Expression of KCC2 in rat cerebellum and hippocampus.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Anti-KCC2 (SLC12A5) Antibody (#AKT-005), (1:1000), followed by goat anti-rabbit-AlexaFluor-488. A. KCC2 immunoreactivity in the cerebellum (green) is detected in the granule layer (GL) and molecular layer (MOL). B. KCC2 staining in the hippocampal dentate gyrus region (green) is observed in the outer molecular layer (OML) and the hilus (H). Cell nuclei are stained with DAPI (blue).

KCC2 (K+-Cl−-cotransporter 2) is a glycoprotein neuron-specific cotransporter and a member of the cation-chloride co-transporter (CCC) family encoded by the Slc12a5 gene. KCC2 is responsible for maintaining low Cl− levels in neurons using the potassium gradient. In addition, KCC2 regulates the formation, functional maintenance and plasticity of glutamatergic synapses. The proper inhibitory functions of GABA are maintained by KCC2 since GABA is dependent on the Cl− driving force promoted by the intracellular concentration of Cl− 1,2.
KCC2 has a predicted structure of 12 transmembrane segments, six extracellular loops flanked by a short intracellular amino terminal and a long intracellular carboxy-terminal1,2.
KCC2 protein expression is detected in the central nervous system including the spinal cord, thalamus, cerebellum, hippocampus, cortical structures and the auditory brainstem1.
Human KCC2 mutations are associated with severe early-onset epileptic encephalopathy and febrile seizures1,2.
Anti-KCC2 (SLC12A5) Antibody (#AKT-005) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot and immunohistochemistry applications. It has been designed to recognize KCC2 from human, rat, and mouse samples.
Multiplex staining of KCC2 and GABA(A) α1 Receptor in rat cerebellum.Immunohistochemical staining of perfusion-fixed frozen rat brain sections using rabbit Anti-KCC2 (SLC12A5) Antibody (#AKT-005), (1:400) and Guinea pig Anti-GABA(A) α1 Receptor (extracellular) Antibody (#AGA-001-GP), (1:400). A. KCC2 immunoreactivity (green) is detected in both the granule layer (GL) and the molecular layer (MOL). B. GABA(A) α1 receptor staining (red) is observed mainly in the granule layer (GL). C. Merge of the two images demonstrates colocalization in the granule layer (arrows). Cell nuclei are stained with DAPI (blue).
