    MiRP1 Antibody (H-4) is a mouse monoclonal IgG1 kappa light chain antibody that detects MiRP1 of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). MiRP1 (H-4) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. MiRP1, also known as KCNE2, plays a crucial role in regulating cardiac and neuronal excitability by modulating voltage-gated potassium channels. MiRP1 interacts with HERG channel, essential for cardiac repolarization, and proper function is vital for maintaining normal heart rhythm. Mutations in MiRP1 can lead to congenital long QT syndrome, a condition increasing risk of life-threatening arrhythmias. MiRP1 also modulates KCNQ2 channels in the brain, influencing neuronal signaling and excitability. Human MiRP1 gene is located on chromosome 21q22.12, and expression is critical for both cardiac and neuronal health, making MiRP1 a significant target for research in cardiac arrhythmias and neurological disorders.
