Cardiac troponin C belongs to the EF-hand superfamily of calcium-binding proteins and plays an essential role in the regulation of muscle contraction and relaxation.
Catalog #T8665-20F
Three troponin I genes have been identified in vertebrates that encode the isoforms expressed in adult cardiac muscle (TNNI3), slow skeletal muscle (TNNI1) and fast skeletal muscle (TNNI2), respectively. Skeletal isoforms of Troponin I were suggested to be used as markers of acute and chronic skeletal muscle injuries.
Dimers and Aggregates 1% as determined by silver-stained SDS-PAGE gel analysis.
Endotoxin 0.1ng/ug (IEU/ug) of human TnI.
