Key result
Novel Bis-fura-2 protocol successfully measures myofilament calcium sensitivity at physiological temperature in rat cardiac trabeculae.
Why the study?
A technique to assess myofilament calcium sensitivity under physiological temperature in intact cardiac trabeculae was lacking.
This novel technique allows for the measurement of myofilament calcium sensitivity at physiological temperatures in intact cardiac trabeculae, enabling more accurate physiological assessments.

Enables physiological-temperature myofilament Ca²⁺ sensitivity assays in intact myocardium; leaves open translation to human disease models.
Varian et al. (2006) studied this question. Novel protocol using Bis-fura-2 and high K+ contractures was evaluated on Steady-state force-[Ca2+]i relationship. A novel protocol using Bis-fura-2 and high K+ contractures successfully measured myofilament calcium sensitivity at physiological temperature in intact rat cardiac trabeculae.
