KV4.3 Antibodies

Santa Cruz Biotechnology delivers a wide array of KV4.3 monoclonal antibodies for research focused on understanding voltage-gated potassium channels. KV4.3 monoclonal antibodies are validated for multiple applications, including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). KV4.3, also known as KCNB3, is a voltage-gated potassium channel that plays a critical role in regulating neuronal excitability and cardiac action potentials. Proper functioning of KV4.3 is essential for maintaining the electrical balance in cells, influencing processes such as muscle contraction and neurotransmitter release. Dysregulation of KV4.3 has been linked to various cardiovascular conditions, including arrhythmias and heart failure. Research has also shown KV4.3's involvement in neurological conditions, particularly in cases of altered neural signaling and cognitive function. Understanding KV4.3's molecular mechanisms can provide valuable insights into potential therapeutic strategies for both cardiovascular and neurological disorders. Current research continues to uncover new aspects of KV4.3's function in cellular signaling pathways and disease progression. Santa Cruz Biotechnology monoclonal antibodies support researchers worldwide in advancing scientific understanding of KV4.3's role in human health and disease treatment.
