• protein
  • To confirm that the homologous recombination event resulted in a allele for protein expression, myofibrils were purified from tibialis anterior, which in +/+ mice expresses high levels of MyHC-IId/x and IIb. (nih.gov)
  • length
  • Based on the framework of sliding-filament theory and on the cross-bridges dynamics, a mathematical model for the simulation of the force response and length change of individual myofibril is presented. (springer.com)
  • several
  • Myofibrils which lengthen by several per cent in the presence of ATP and magnesium ions were prepared by teasing indirect flight muscle of Drosophila in solutions containing ethylenediaminetetraacetate. (rupress.org)
