Multivesicular Vesicles: Preparation and Applications

preparation and characterization of multivesicular vesicles (mvvs) containing gentamicin as a depot drug delivery system

EXTRACELLULAR VESICLES AND THEIR THERAPEUTIC APPLICATIONS: A REVIEW

Background & Aims: Extracellular vesicles are double phospholipid layer vesicles releasing from several cells.  These particles contain bio-molecules including mRNA, miRNA, DNA, proteins, and lipids which play a pivotal role in the cell to cell communication. Once delivered, they participate to change target cell function, fate, morphology, differentiation, and growth. The present study is a re...

Cytochemical Staining of Multivesicular Body and Golgi Vesicles

To investigate the origin and nature of vesicles found within multivesicular bodies (mvb), the cytochemical staining properties of mvb vesicles were compared with those of other cytoplasmic vesicles, i.e. those associated with the Golgi complex and endocytic vesicles found near the apical cell surface. Rat epididymal tissue was stained in unbuffered OsO(4) for 40-48 hr, and the distribution of ...

PREPARATION AND APPLICATIONS OF FLUORESCENT POLYGLUTARALDEHYDE IMMUNOMICROSPHERES

Aqueous glutaraldehyde has been polymerized under alkaline conditions in the presence of a surfactant to yield microspheres of varied diameters. Microbeads of a nominal 300 nm diameter, made fluorescent via fluoresceinisothiocyanate, were used as a carrier of rabbit anti-human red blood cell antibodies. Specific labeling of the human red blood cells as well as diagnostic use of these fluor...

Preparation of Large Monodisperse Vesicles

Preparation of monodisperse vesicles is important both for research purposes and for practical applications. While the extrusion of vesicles through small pores (approximately 100 nm in diameter) results in relatively uniform populations of vesicles, extrusion to larger sizes results in very heterogeneous populations of vesicles. Here we report a simple method for preparing large monodisperse m...
