FITC-Trehalose (Fluorescein isothiocyanate-trehalose) is a fluorescent derivative of trehalose. In nature, trehalose can be found in plants, animals, and microorganisms that is broken down into glucose by the catabolic enzyme trehalase. FITC-trehalose has a molecular weight of 731.7 Da and is supplied as a yellow powder. All the batches are checked for molecular weight, degree of substitution, loss on drying and free FITC.

Trehalose, also known as mycose or tremalose, is a natural α-linked 1,1-glucose disaccharide that lacks a reducing end and is very resistant to acidic hydrolysis.

Spectral data
FITC-trehalose has an excitation maximum of 490 – 495 nm and an emission maximum of 520 ± 5 nm.

Storage and stability
FITC-trehalose is stable for more than 6 years when stored dry in well-sealed containers at ambient temperature.

FITC-trehalose dissolves readily in water.

A number of application areas of trehalose are currently being explored, for example treatments of amyloidosis, depression and dry eyes. Read more about applications here.
