Immunogen R4A is a mouse monoclonal IgG1 antibody derived by fusion of SP2/0-Ag14 mouse myeloma cells with spleen cells from a mouse immunized with a cytoskeletal extract of chicken gizzard.
Clone R4A
Isotype IgG1
Specificity Human, canine, feline, chicken, swine, monkey. Not reactive with rat.
Purification Culture supernatant
Alternative Name Smoothelin
Background Smoothelin is a constituent of the smooth muscle cell (SMC) cytoskeleton. Antibodies directed to smoothelin are useful tools to monitor SMC differentiation. Smoothelin is exclusively expressed in fully differentiated (contractile) SMCs. RNA and protein analyses revealed a broad species distribution of this protein. Cells with SMC-like characteristics, such as myofibroblasts and myoepithelial cells, as well as skeletal and cardiac muscle do not contain smoothelin. Confocal scanning laser microscopy of tissue sections and cells in culture show a filamentous organization of smoothelin colocalizing with actin stress fibers. In immunoblots two molecular weight isoforms are detected i.e. a 59 kDa isoform specific for visceral SMC (smoothelin A), and an isoform with a molecular weight of approximately 100 kDa in vascular SMC (smoothelin B). Human smoothelin is encoded by a single copy gene which is located on chromosome 22.
Research Area Organogenesis, Cytoskeleton
Application Notes R4A reacts with the 59 kDa and 100 kDa protein, corresponding to smoothelin A and B, respectively, which are exclusively found in smooth muscle cells. R4A is suitable for immunoblotting and immunohistochemistry on frozen and paraffin-embedded tissues and for staining with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent. For staining paraffin-embedded tissues pretreatment in 10 mM citrate buffer (pH 6.0) and heating for 3 times 5 minutes in a microwave is required. Can be diluted to 1:50.
