Our Anti-Potassium Channel, Voltage-Gated, Kv3.1 Subunit (Ser503) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects hamster, mouse and rat Potassium Channel, Voltage-Gated, Kv3.1 Subunit (Ser503) and is antigen affinity purified from pooled serum. It is great for use in WB, IHC, ICC.
Immunostaining of Chinese Hamster Overy (CHO) cells stably transfected with KV3.1b gene with the phospho-Ser503 Kv3.1 subunit antibody (Cat. p1550-503, green, 1:400). The image on the right shows cells that have been treated with the protein kinase C activator PMA (500nM) while the control cells are on the left.
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).
