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-Myosin (Skeletal, Fast) (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.
Specificity
Monoclonal Anti-Myosin (Skeletal, Fast) specifically binds to an epitope in adult rat skeletal myosin heavy chains IIa, IIb and IId (IIx) (in fast-twitch fibers)†. The antibody product is also reactive in humans, bovines, cats, rabbits, mice, guinea pigs and chickens.
Immunogen
rabbit muscle myosin.
Application
Monoclonal Anti-Myosin (Skeletal, Fast) Alkaline Phosphatase antibody produced in mouse has been used for the detection and localization of skeletal muscle fast and neonatal myosins using immunohistochemistry. It may be used in muscle fiber typing, in studies of in vivo and in vitro muscle development and in the diagnosis of rhabdomyosarcomas.
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.
Biochem/physiol Actions
Myosin (Skeletal, Fast) is useful not only in fiber typing but also in detection of myogenic tumors. It enables retrospective as well as prospective fiber typing using formalin-fixed, paraffin-embedded material.
Myosins are motor proteins that interact with actin filaments to regulate cell movement. Myosins also modulate cell shape and signaling. Skeletal muscle myosins have three ′fast′ myosin heavy chains isoforms (IIa, IIx, and IIb), a ′slow′ beta-myosin heavy chain isoform and three major myosin light-chain (MLC) isoforms. These myosin isoforms regulate skeletal muscle shortening.
Physical form
Solution in 0.05 M Tris buffer, pH 8.0, containing 1% bovine serum albumin, 1 mM MgCl2, 50% glycerol, and 15 mM sodium azide.

Peripheral neuropathy is one of the most common complications of diabetic hyperglycaemia. Insulin-induced hypoglycaemia (IIH) might potentially exacerbate or contribute to neuropathy as hypoglycaemia also causes peripheral neuropathy. In rats, IIH induces neuropathy associated with skeletal muscle changes. Aims of
