MA3-910 detects sarcoplasmic or endoplasmic reticulum calcium 2 (SERCA2) ATPase from bovine, canine, human, pig, rabbit and rat tissues. This antibody does not detect frog SERCA2 ATPase (J. Biol. Chem., Feb 2001; 276: 3911 - 3919). MA3-910 detects SERCA2 ATPase and does not discriminate between the two isoforms.
MA3-910 has been successfully used in Western blot, immunofluorescence, immunocytochemistry, and immunohistochemistry. By Western blot, this antibody detects an ~110 kDa protein representing SERCA2 ATPase from canine skeletal muscle triad preparations. Immunofluorescence staining of SECRA2 ATPase in rabbit skeletal muscle with MA3-910 results in strong labeling of the entire type I (slow) myofiber consistent with sarcoplasmic reticulum localization.
MA3-910 is not recommended for Western blot detection of rat SERCA2.
The MA3-910 antigen is purified canine cardiac sarcoplasmic reticulum.
ATP dependent calcium pumps are responsible, in part, for the maintenance of low cytoplasmic free calcium concentrations. The ATP pumps that reside in intracellular organelles are encoded by a family of structurally related enzymes, termed the sarcoplasmic or endoplasmic reticulum calcium (SERCA) ATPases. The SERCA1 gene is exclusively expressed in type II (fast) skeletal muscle. The SERCA2 gene is subject to tissue dependent processing which is responsible for the generation of SERCA2a muscle-specific form expressed in type I (slow) skeletal, cardiac and smooth muscle and the SERCA2b isoform expressed in all cell types. The SERCA3 gene is not as well characterized and is found in non-muscle cells.
