Cardiotin is a high molecular weight protein complex (300 kDa) loCated in the mitochondria of cardiomyocytes and skeletal muscle. The cardiotin structure exists of subunits of 60 kDa and 100 kDa, probably in a tetrameric configuRation. Both subunits contain the same amino-terminal 14 amino-acid sequence, showing high homology to Human skeletal muscle α-actinin. During cardiac contractile dysfunction and myocard cell differentiation, the cardiotin distribution is affected. Compared to other structural proteins, cardiotin is one of the first to respond to insults (ischemia, fibrillation) that influence the functional status of cardiomyocytes.
R2G is a mouse monoclonal IgM antibody derived by fusion of SP2/0-Ag14 mouse myeloma cells, with spleen cells from a mouse immunized with a total protein extract of chicken gizzard.
Each vial contains 0.1 ml monoclonal antibody in PBS containing 0.09% sodium azide. The antibody is purified by ammonium sulphate precipitation and will threfore contains fetal calf serum derived protein contaminants
Purification Method: Ammonium sulphate precipitation
Concentration: 1 mg/ml
R2G reacts with cardiotin, a mitochondrion-associated protein, which is present in cardiomyocytes and skeletal muscle.
R2G is useful for immunohistochemistry on frozen and paraffin-embedded tissue and immunoblotting. In immunoblotting assays R2G reacts with the 300 kDa cardiotin protein complex and its 100 kDa and 60 kDa subunits. Recommended range is 1:25 – 1:100 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent. Optimal antibody dilution for immunoblotting applications should be determined by titration.
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
Shipping Conditions: Ship at ambient temperature.
