FITC-Dextran (MW 70000) (solution)

FITC-Dextran (MW 70000) (solution) is a compound belonging to the class of fluorescent dyes. It is commonly used in biomedical research as a tracer molecule to label and track cells or other biological matter. FITC-Dextran consists of fluorescein isothiocyanate (FITC) and dextran, a complex carbohydrate derived from starch. The combination of the two creates a stable fluorescent tracer that can be viewed under a microscope or quantified using specialized detection instruments.

Biological Activity

Description

In Vitro

FITC-Dextran (MW 70000) is a fluorescent probe for fluorescein isothiocyanate (FITC) dextran (Ex=495 nm; Em=525 nm). FITC-Dextran (MW 70000) can be used as a marker to reveal heat shock-induced cell damage and to study the early and late stages of apoptosis. FITC-Dextran (MW 70000) can also be used for cell permeability studies, such as blood-brain barrier permeability and determination of the extent of blood-brain barrier disruption^[1]^[2]^[3]. Storage: protect from light.

In Vivo

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
For intestinal barrier function assay^[5]
1. Fast mice for 4 h.
2. Orally gavage mice with FITC-Dextran MW 70000 (0.6 mg/g).
3. Measure fluorescence intensity of plasma in 4 h (excitation nm/emission 520 nm).

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.
