MA3-926 detects sodium/calcium exchanger from human, canine, rabbit, mouse, guinea pig and rat kidney and cardiac tissues.
MA3-926 has been successfully used in Western blot, immunofluorescence, immunohistochemistry, and immunoprecipitation procedures. By Western blot, this antibody detects a 120 kDa protein representing the sodium/calcium exchanger from guinea pig cardiac extract. The bands seen at 70 kDa and 160 kDa represent a proteolytic fragment and non-reduced exchanger respectively. MA3-926 is not recommended for Western blot procedures of rat tissues. Immunohistochemical staining of the sodium/calcium exchanger in rat heart with MA3-926 results in staining of the plasma membrane and intense staining of cardiac T-tubular membrane.
The MA3-926 antigen is purified canine cardiac sodium/calcium exchanger. This antibody recognizes an epitope between amino acids 371-525, which is on the intracellular side of the plasma membrane.
Ca2+ plays a critical role in intracellular signaling and thus regulation of calcium balance is critical for the maintenance of this signaling function. The plasma membrane Na+/Ca2+ (NaCX) exchangers mediate Na+-dependent Ca2+ efflux in a wide variety of cell types. NaCX can move Ca2+ either into or out of cells, depending on the net Na+, Ca2+, and K+ gradient across the membrane. In mammals, at least 5 distinct genes code for the exchangers: Three NaCX (NaCX-1, NaCX-2, and NaCX-3), and two in the NaCKX family (NaCKX-1 and NaCKX-2). NaCX-1 is most prominently expressed in the heart where it plays a major role in excitation-contraction coupling (Matsuoka et al., 1993). NACX-1 may also be a target for protection of the heart and brain from ischemia and reperfusion injury (Hagihara et al., 2005; Bano et al., 2005; Choi, 2005).
