Abstract
Current methods of SDS-PAGE for cardiac myosin heavy-chain (MHC) isoforms are complex and require more than 24 h. The aim of the current study was to improve the methodology of gel electrophoresis for faster and efficient separation of MHC isoforms. Rat ventricle and soleus tissues were subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) using tris-glycine buffer. Matrix-assisted laser desorption ionization (MALDI)-time of flight (TOF)-mass spectra (MS) of protein bands was done to identify α,β-MHC. Clear separation of α,β-MHC isoforms on SDS-PAGE was achieved and identity was confirmed by MALDI-TOF-MS. The smaller gel system drastically reduced the total run time to 2 h. The present method provides a simple, quick, and efficient protocol for cardiac α,β-MHC separation.
