Orai2 Antibody (C-12) is a mouse monoclonal IgG2b antibody that detects Orai2 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Orai2, also known as CBCIP2 or TMEM142B, is a 254 amino acid multi-pass membrane protein that is crucial for store-operated calcium entry, a vital process that facilitates calcium influx and replenishes calcium stores that have been depleted by inositol 1,4,5-trisphosphate and other calcium-mobilizing agents. Orai2 is primarily located in the plasma membrane, where Orai2 plays a significant role in mediating calcium influx through calcium release-activated calcium (CRAC) channels, particularly in T-cells, which are essential for the immune response. The interaction of Orai2 with the calcium sensor Stim1 enhances the calcium-selective current, underscoring Orai2′s importance in maintaining cellular calcium homeostasis and regulating various physiological processes. Anti-Orai2 antibody (C-12) is an invaluable tool for researchers studying calcium signaling pathways and their implications in immune function and other cellular activities.
