FURA 2 PENTAPOTASSIUM SALT Chemical Properties,Usage,Production

Description

Fura-2 is a ratiometric fluorescent calcium indicator that can be used to detect calcium in cells. It is a pentacarboxylate that displays excitation maxima of 340 and 380 nm at high and low calcium concentrations, respectively, when the emission is fixed at 510 nm, enabling determination of ratiometric measurements of calcium influx in live cells.

Uses

A very sensitive fluorescent calcium chelator that exhibits a spectral shift in excitation maxima on binding calcium. Fura-2 has become the dye of choice for ratio-imaging microscopy, in which it is more practical to change excitation wavelengths than emi

Uses

FURA-2 Pentapotassium Salt (Technical Grade) is a cell impermeable fluorescent probe for magnesium.

storage

-20°C
