🧬 Background: What Is KCNQ1?
KCNQ1, also known as KvLQT1, encodes a potassium ion channel subunit that plays a critical role in cardiac action potential repolarization. Mutations in KCNQ1 are associated with:
- Type 1 Long QT Syndrome (LQT1)
- Familial Atrial Fibrillation
- Jervell and Lange-Nielsen Syndrome
Expression is also found in epithelial tissues including the kidney, colon, pancreas, and inner ear.
🧫 Application Data
- Western Blot (WB): 1:1,000 dilution recommended for lysates from heart, kidney, or epithelial tissues
- IHC (Paraffin-embedded): 1:200 dilution after antigen retrieval
- Immunofluorescence (IF): 1:250 for confocal microscopy of membrane localization
