Rat Liver Tritosomes

Current Promotions

Rat-Liver-Tritosomes3.jpgRat liver tritosomes are hepatic lysosomes that have been loaded with Tyloxapol (Triton WR 1339), a non-ionic surfactant. Tyloxapol is taken up by hepatocytes through endocytosis and is trafficked to lysosomal compartments. Tyloxapol containing lysosomes exhibit decreased density and can be more efficiently isolated away from mitochondria and contaminating cellular organelles that have overlapping densities with native lysosomes (1-3). 

The use of tritosomes is well-established and has been classically used to study lysosomal composition, function, and disease (4-6). More recently they have become a powerful reagent to assess the in vitro stability and release of small molecular moieties conjugated to nano particles, polymers and antibodies that enter cells through the endosome-lysosome pathway (7-10).
 
Features and Benefits:
  • Highly purified
  • Characterized for lysosome specific enzymatic activity
  • Less complex than in vivo models
  • More representative than using individually expressed/purified enzymes
