In cardiac muscle, the action potential is caused by opening of three types of channels: 

Voltage activated fast sodium channels 

L-type calcium channels (slow calcium channels or calcium-sodium channels)

Voltage activated potassium ion channels

The bacterium Streptococcus pyogenes, for example, expresses cell-wall proteins called M antigens. Antibodies produced to streptococcal M antigens have been shown to cross-react with several myocardial and skeletal muscle proteins and have been implicated in heart and kidney damage following streptococcal infections.

Acrylamide gels can be made with a content of between 3% and 30% acrylamide Low concentration are used to where free movement of the proteins is required without any noticeable frictional effect such as flat-bed isoelectric focusing or the stacking gel system of an SDS–polyacrylamide gel.
