32/K Channel

Cellular excitability is modulated by the precise function of voltage-sensitive ion channels. Large conductance potassium channels (Maxi-K) are unique in that they are sensitive to transmembrane  potential and intracellular Ca2+ concentrations. These channels, important for neuronal firing and vascular tone, share many features with voltage-dependent Na+, Ca2+, and K+ channels. Among these are the S4 region, a motif with a repeated triple sequence of one positively charged amino acid and two hydrophobic amino acids. This region is thought to be the voltage sensor. Maxi-K is subject to complex metabolic control control that also involves G proteins and phosphorylation/dephosphorylation reactions. This type of K+ channel is composed of two subunits, the pore-forming α subunit (hslo) and the regulatory β subunit. The α subunit is subject to direct phosphorylation by cyclic GMP-dependent protein kinase (PKG) and dephosphorylation by protein phosphatase 2A. The fact that the α subunit of Maxi-K channels is a substrate of PKG supports the idea that these channels perform an important function in the cellular response to potent vasodilators, such as nitrocompounds and atrial natiuretic peptide.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
