Lysosome Isolation Kit (ab234047) provides a procedure for isolating an enriched or purified lysosomal fraction from animal tissues and cultured cells by differential centrifugation followed by density gradient centrifugation.

Lysosomes are membrane-bound cell organelles found in most animal cells (except red blood cells). Lysosomes are spherical vesicles containing hydrolytic enzymes capable of breaking down different kinds of biomolecules, including proteins, nucleic acids, carbohydrates, lipids, and cellular debris. They are known to contain over 50 different enzymes, which are active under acidic conditions. Thus, lysosomes act as the waste disposal system of the cells by digesting unwanted materials in the cytoplasm.
