Using the calcium sensitive probe Fura 2, we determined the 340/380 nm wave-length ratios by measuring alterations in calcium homeostasis in isolated myotubes from cultured skeletal muscle specimens. More recently, genetically-encoded calcium indicators based on spectral variants of the green fluorescent protein, such as Cameleons, have supplemented the use of Fura-2 and other small molecule dyes for calcium imaging, but Fura-2 remains faster. The first time we&39;ve used FURA-2 we&39;ve been getting an excellent excitation spectrum (fig 1), which lead to a Kd value of about 30 nM, and great predictability of calcium concentration in solution.
