Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca2+. They have uses in many calcium signaling investigations, including measuring Ca2+ in cells and tissues that have high levels of autofluorescence and also for detecting Ca2+ release generated by photoreceptors and photoactivatable chelators. Cells may be loaded with the AM ester forms of these calcium indicators by adding the dissolved indicator directly to dishes containing cultured cells. The fluorescence signal from these cells is generally measured using fluorescence microscopy.

Calcium Indicator (AM Ester) Specifications:

  • Label (Ex/Em of Ca2+–bound form): X-rhod-1 (580/602 nm)
  • Fluorescence intensity increase upon binding Ca2+: >100 fold
  • Kd for Ca2+ in the absence of Mg2+, in buffer: ∼700 nM
  • Exhibit fluorescence increase upon binding Ca2+ with little shift in wavelength

    Using TPEN to Control Heavy Metal Cations

    In addition, BAPTA-based indicators such as these bind various heavy metal cations (e.g., Mn2+, Zn2+, Pb2+) with substantially higher affinity than Ca2+. Perturbations to calcium measurements caused by presence of these ions can be controlled using the heavy metal-selective chelator TPEN.

    More Choices for Fluorescent Calcium Indicators

    We offer a large selection of Molecular Probes™ calcium indicators for use in various experimental scenarios, for example dextran versions for reduced leakage and compartmentalization and BAPTA conjugates for detecting high-amplitude calcium transients. For more information, review Fluorescent Ca2+ Indicators Excited with Visible Light—Section 19.3 in the Molecular Probes™ Handbook.

    Mitochondrial modulation of Ca2+ -induced Ca2+ -release in rat sensory neurons.
    Authors:Jackson JG, Thayer SA
    Journal:J Neurophysiol
    PubMed ID:16760347
    'Ca2+ -induced Ca2+ -release (CICR) from ryanodine-sensitive Ca2+ stores provides a mechanism to amplify and propagate a transient increase in intracellular calcium concentration ([Ca2+]i). A subset of rat dorsal root ganglion neurons in culture exhibited regenerative CICR when sensitized by caffeine. [Ca2+]i oscillated in the maintained presence of 5 mM ... More
