Used in biomedical research to detect and quantify Human Membrane Potassium Channel Protein (often referred to as Poticulin) in cell lysates, tissue extracts, or biological fluids such as serum and plasma. This ELISA kit enables researchers to study the expression levels of potassium channel proteins involved in cellular electrical activity, particularly in excitable cells like neurons and cardiac myocytes. It is widely applied in neuroscience, cardiology, and immunology research to investigate ion channel regulation, disease mechanisms (such as arrhythmias, epilepsy, or autoimmune channelopathies), and the effects of pharmaceutical compounds on ion channel expression. The assay provides a sensitive and specific method for high-throughput screening in both basic research and drug development settings.
