General description

Myosin is a cytoskeletal protein responsible for muscle contraction, muscle filament sliding and regulation of ATPase activity. Monoclonal anti-myosin (Light Chains 20 kDa) antibody diluted 1:200 can be used to detect MLC20. It is also useful in staining (1:10,000) 2D slab gels. Anti-myosin(Light Chains 20 kDa) antibody reacts specifically with 20 kDa light chain of chicken gizzard, chicken intestine and pig stomach myosin which is SDS, heat denatured and reduced but not with intact myosin molecule in its native state.


Monoclonal anti-myosin (Light Chains 20 kDa) antibody can be used in immunoblotting and western blotting.
