Product Overview
This rabbit polyclonal antibody targets potassium voltage-gated channel subfamily A member 1 (gene KCNA1) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 56.5 kDa, and the supplier reports an observed band at about 90 kDa.
Kv1.1 (KCNA1) is a Shaker-type voltage-gated potassium channel subunit expressed mainly in the brain and peripheral nerves. Four subunits, alone or mixed with other Kv1 family members, form a potassium-selective pore that opens on depolarization, helping to repolarize the membrane and limit neuronal hyperexcitability. Mutations in KCNA1 cause episodic ataxia type 1, and it is studied in neuronal excitability and epilepsy research.

Immunogen
Recombinant human Kv1.1 potassium channel/KCNA1 fragment (Met1–Val495), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places potassium voltage-gated channel subfamily A member 1 in the cell membrane, membrane, cell projection and cytoplasmic vesicle. Tissue expression noted by UniProt (human): Detected adjacent to nodes of Ranvier in juxtaparanodal zones in spinal cord nerve fibers, but also in paranodal regions in some myelinated spinal cord axons (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
