Canal de potasio
Los canales de potasio son un grupo diverso de proteínas de membrana que facilitan el flujo de iones de potasio (K+) a través de la membrana celular. Estos canales desempeñan un papel crucial en el mantenimiento del potencial de membrana en reposo, la regulación del volumen celular y el control de la excitabilidad de las neuronas y las células musculares. Los canales de potasio están involucrados en varios procesos fisiológicos, incluyendo la regulación del ritmo cardíaco, la secreción de insulina y la liberación de neurotransmisores. La disfunción de los canales de potasio está relacionada con condiciones como arritmias, epilepsia e hipertensión. En CymitQuimica, ofrecemos una amplia gama de moduladores de canales de potasio para apoyar su investigación en electrofisiología, salud cardiovascular y neurobiología.
