Antigen/Purification: ExpandCollapse

The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser940 of rat KCC2.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho- and non-phosphopeptide affinity columns.

Biological Significance: ExpandCollapse

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 Ser940 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).

100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
