This product is not considered lysine-fixable. The material would have to be chemically treated in order to be suitable. Typically, dextrans used to prepare lysine-fixable products are anionic (see product 90718). Should it be of interest, product B9139 is a Biotin-dextran, lysine-fixable product option.

Application
FITC-dextran is used in cardiovascular, microcirculation, perfusion, cell monolayer and cell membrane permeability research as fluorescent flux tracer compound that supports the measurement of processes such as blood flow, membrane damage, vascular drainage and renal elimination. Small FITC-dextrans are also used to measure processes such as endocytosis and cell junction permeability. FITC-dextran 70 kDa (FD-70) may be used as a model compound for development of methods to deliver molecules into protoplasts and to study drug release from structures such as hydrogels and liposomes. FD-70 may be used in microvascular and cell monolayer permeability studies.
Destrano marcato con isotiocianato di fluoresceina per il possibile utilizzo negli studi di perfusione negli animali.
Other Notes
Similar to FD-70, but produced by Sigma.
