MA3-925 detects ryanodine receptor (RyR)-1 and RyR-2 isoforms in amphibian, chicken, bovine, canine, fish, human, non-human primate, mouse, rabbit, mink, rat and sheep tissues. In chickens this antibody detects the alpha, beta and cardiac isoforms. This antibody also detects RyR-3 in mouse cells. In frog, MA3-925 detects the alpha and beta isoforms and in fish it detects the alpha isoform.
MA3-925 has been successfully used in Western blot, immunohistochemistry, immunofluorescence and immunoprecipitation procedures. By Western blot, this antibody detects a 565 kDa protein representing RyR from rat skeletal muscle extracts. In non-mammalian vertebrates, a doublet is seen at 565 kDa representing the alpha and beta isoforms of the receptor. Immunohistochemical staining of RyR in chicken brain with MA3-925 results in intense staining of cerebellar Purkinje neurons.
The MA3-925 antigen is partially purified chicken pectoral muscle ryanodine receptor.
Ryanodine receptors have been shown to play critical roles in the intracellular Ca2+ signaling occurring during cell activation in muscle cells and non-muscled cells. Ryanodine receptor, ~500 kDa, can be isolated from a variety of cell types such as lymphocytes, macrophages, granulocytes, fibroblasts, epithelial, endothelial cells, skeletal muscles, cardiac muscle and brain tissues.
