Ready-to-use ELISA kits are available for the detection of HNSPC, an alias of the protein, potassium voltage-gated channel subfamily Q member 2. The official gene symbol is KCNQ2. The protein, with a mass of 95.8 kDa and length of 872 residues, is reported to be membrane-associated. It is a member of the Potassium channel family, KQT (TC 1.A.1.15) subfamily, Kv7.2/KCNQ2 sub-subfamily and may be known by other names, including: EBN1, EBN, voltage-gated potassium channel subunit Kv7.2, potassium channel voltage gated KQT-like subfamily Q member 2, neuroblastoma-specific potassium channel subunit alpha KvLQT2, and HNSPC.
