Western blot of rat hippocampal lysate showing specific labeling of the ~135 kDa KCC2 protein phosphorylated at Ser940 in the first lane (-). Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen in the second lane (+), but not by the corresponding non-phosphopeptide (not shown).
We are the original manufacturer of our rabbit polyclonal KCC2 (Ser940) phosphospecific antibody, affinity purified from pooled serum. It is excellent for use in WB and IP.

Target Description: KCC2 is widely thought to be expressed exclusively in neurons where it is responsible for maintaining low intracellular chloride concentration to drive hyperpolarizing post-synaptic responses to the inhibitory neurotransmitters GABA and glycine. Serine 940 on KCC2 has been shown to be phosphorylated by PKC and has further been demonstrated to be the major site for PKC-dependent phosphorylation for full length KCC2 molecules when expressed in HEK-293 cells as phosphorylation of Ser-940 increased the cell surface stability of KCC2 in this system by decreasing it’s rate of internalization from the plasma membrane (Lee et al., 2007).
