bs-70227R

DATASHEET

Host: Rabbit

Target Protein: Potassium Channel, Voltage-Gated, Kv3.1 Subunit (Ser503)

Specificity: Specific for endogenous levels of the ~100 kDa Kv3.1 voltage-gated potassium channel protein phosphorylated at Ser503.

Modification Site: Ser503

Clonality: Polyclonal

Isotype: IgG

Entrez Gene: 25327

Swiss Prot: P25122

Source: The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser503 of the rat voltage-gated potassium channel Kv3.1, conjugated to keyhole limpet hemocyanin (KLH).

Purification: Antigen Affinity purification from Pooled whole antiserum

Storage Buffer: 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Storage: 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.

Background:

Voltage-gated K+ channels are important determinants of neuronal membrane excitability. Moreover, differences in K+ channel expression patterns and densities contribute to the variations in action potential waveforms and repetitive firing patterns evident in different neuronal cell types (Maletic-Savatic et al., 1995; Pongs, 1999; Blaine and Ribera, 1998; Burger and Ribera, 1996). The Kv3.1 potassium channel is expressed at high levels in neurons that characteristically fire rapid trains of action potentials (Gan et al., 1999). Particularly high levels of this channel are found in neurons of the auditory brainstem. These neurons appear to participate in neural circuits that determine the intensity and timing of auditory stimuli and use this information to determine the location of sounds in space (von Hehn et al., 2004).
