Product Overview
This rabbit polyclonal antibody recognizes potassium voltage-gated channel subfamily KQT member 2 (gene KCNQ2) in human, mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 95.8 kDa, and the supplier reports an observed band at about 97 kDa.
KCNQ2 (Kv7.2) is a voltage-gated potassium channel subunit that combines with KCNQ3 to form the neuronal M-channel. The resulting M-current activates slowly near the resting potential and limits repetitive firing, and it is suppressed by muscarinic receptor signaling. KCNQ2 variants cause benign familial neonatal seizures and more severe epileptic encephalopathies, and the channel is a target of antiseizure drug research.

Immunogen
Recombinant human KCNQ2 fragment (Met371–Asp408), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places potassium voltage-gated channel subfamily KQT member 2 in the cell membrane. Tissue expression noted by UniProt (human): In adult and fetal brain. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
