Used in biomedical research to quantify levels of the L-type calcium channel α2 subunit (CACNA2D1) in tissue extracts, cell lysates, or biological fluids. This ELISA kit enables researchers to study the expression and regulation of voltage-gated calcium channels involved in muscle contraction, hormone secretion, and neuronal signaling. It is particularly useful in neuroscience and cardiovascular research, where dysregulation of calcium channels is linked to diseases such as hypertension, arrhythmias, and neuropathic pain. The assay supports high-throughput analysis and provides a reliable tool for evaluating therapeutic interventions targeting calcium channel function.
