Description

General description

Acetoxymethyl (AM) derivative of FURA-PE3 with spectral properties similar to the parent compound. Can be loaded into cells in a manner similar to FURA 2/AM. Hydrolysis by non-specific esterases traps the indicator in the cytosol. Compared to FURA-2, it is retained longer in the cell. Note: 1 set = 10 x 50 µg.

An acetoxymethyl (AM) derivative of FURA-PE3. with spectral properties similar to the parent compound. Can be loaded into cells in a manner similar to FURA 2/AM (Cat. No. 344905). Hydrolysis by non-specific esterases traps the indicator in the cytosol. Spectral properties in the presence of low calcium concentrations (ex. 364 nm, em. 508 nm) differ from those during high calcium conditions (ex. 335 nm, em. 495 nm). Note: 1 set = 10 x 50 µg.
