Fluorescein hydrazide is a sensitive fluorescent probe for Hg²⁺ and Co²⁺ that induces obvious color changes and fluorescence changes. Fluorescein hydrazide can be prepared by the reaction of fluorescein and hydrazine. Fluorescein hydrazide exhibits an excitation wavelength of 508 nM and an emission wavelength of 531 nM[2][3].

Beschreibung

In Vitro

Fluorescein hydrazide forms a complex with Hg²⁺, which in turn triggers structural changes in the Fluorescein hydrazide molecule, causes changes in its absorption and fluorescence spectra, thereby resulting the color and fluorescence intensity of Fluorescein hydrazide solution^[2].
Fluorescein hydrazide can be used for detection of mercury pollution in water, food and biological samples, which can be applied in environmental monitoring, food safety and biomedicine^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
