BTC (tetrapotassium)

• Description:

  BTC tetrapotassium is a low affinity calcium indicator (Kd approximately 7-26 µM) featuring many desirable properties for cellular calcium imaging, including long excitation wavelengths (400/485 nm), low sensitivity to Mg2+, and accuracy of ratiometric measurement[1].
