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.

Aplicación
Dextrano marcado con isotiocianato de fluoresceína para su posible uso en estudios de perfusión en animales.
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.[1] Small FITC-dextrans are also used to measure processes such as endocytosis and cell junction permeability.[2] 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.[3]

Chronic sleep restriction induces blood-brain barrier disruption and increases pro-inflammatory mediators in rodents. Those inflammatory mediators may modulate the blood-brain barrier and constitute a link between sleep loss and blood-brain barrier physiology. We propose that adenosine action on its A2A

Background: Pathological angiogenesis is the hallmark of many vision-threatening diseases. Anti-VEGF is a primary treatment with substantial beneficial effects. However, such agents require frequent intravitreal injections. Our previous work established a method for effectively modifying exosomes (EXOs) for loading therapeutic
