General description
Localizes an epitope on the myosin heavy chain. Stains the fast (type II) and neonatal isomyosin molecules found in skeletal muscle, but does not stain cardiac muscle, smooth muscle or non-muscle myosin in cultured cells. Does react with human rhabdomyosarcomas.
Monoclonal Anti-Skeletal Myosin (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Myosin is a 480,000 dalton protein known to interact with actin in muscle and in non-muscle cells. It contains two identical heavy chains (200,000 daltons each) and four light chains (15,000-26,000 daltons). Myosin molecules consist of two major regions: tails (rods) and heads; they aggregate into filaments through the tail region and interact with actin and with ATP through the head region. Multiple forms of myosin heavy chains exist for each muscle type-skeletal, cardiac, smooth and non-muscle isomyosin forms exist in different types of skeletal muscle, depending on the physiological function of the muscle. These are designated at type I (slow twitch) and type II (fast-twitch). Type II fibers can be further subdivided in types IIA, IIB, and IIC.
Specificity
Monoclonal Anti-Skeletal Myosin is specific for the myosin heavy chain. It does not stain human or animal cardiac or smooth muscle myosin or cells grown by tissue culture (nonmuscle myosin). It has been demonstrated on human skeletal muscle that the antibody stains the fast twitch (type II) isomyosin molecules. Monoclonal Anti-Skeletal Myosin antibody does react with human rhabdomyosarcomas.
Immunogen
rabbit muscle myosin.
Application
Monoclonal Anti-Myosin (Skeletal, Fast) antibody produced in mouse has been used in:
- immunohistochemistry
- immunostaining
- western blotting at a dilution 1:1000 and 1:90000†
- indirect immunofluorescence (dilution 1:400) of formalin-fixed, paraffin-embedded sections of human or animal skeletal muscle tissue preparation.
- dot immunobinding on muscle extracts or purified myosin preparations
The level of mysosin (fast) in serum samples from sportsmen with past injury was determined by western blot using monoclonal mouse anti-myosin (skeletal/fast) as the primary antibody at a dilution of 1:90000.
