Description
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.
- Fluorescence signal from these cells is generally measured using fluorescence microscopy
- Fluorescence intensity increase upon binding Ca2+: >100 fold
- Kd for Ca2+ in absence of Mg2+, in buffer: approximately 320μM
- Exhibit fluorescence increase upon binding Ca2+ with little shift in wavelength
- 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 heavy metal-selective chelator TPEN
