Application

Calcein has been used:
  • in whole cell staining[1]
  • in histomorphometry and micro-computed tomography[2]
  • to label active bone-forming surfaces[3]

Biochem/physiol Actions

Calcein is a calcium-dependent fluorescent molecule. It is mainly required to study bone metabolism under in vivo conditions and helps in the staining of pit area under in vitro conditions.[4] Calcein is used for the fluorometric determination of calcium and EDTA (ethylenediaminetetraacetic acid) titration of calcium.[5]

Questions

1–6 of 6 Questions  
  1. Is this calcein (C0875) membrane-permeable or membrane-impermeable?

    1 answer
    1. No in-house testing has been performed to determine if Calcein is membrane permeable or membrane impermeable. The literature suggests Calcein appears to be membrane impermeable. Conn's Biological Stains, 10th Edition, page 250 states, "entry of the dye into cells may be achieved by direct insertion of the hydrophilic calcein, or by the uptake of calcein AM with intracellular formation of calcein."

  2. What are the excitation and emission wavelengths of Calcein, Product C0875?

    1 answer
    1. Conn's Biological Stains, 10th Edition states excitation is at 494 nm in aqueous solutions at pH 9; the emission maximum is 517 nm. Depending upon the pH of the solution, slightly different values have been reported in the literature.
