Abstract
Here, we report our step-by-step protocol for superparamagnetic nanoparticle (SPMNP)-based endosome and lysosome isolation from HeLa. Briefly, we synthesized SPMNP 1.0 with iron oxide (Fe3O4) core using thermal decomposition method. Further, we performed ligand-exchange strategy for surface functionalization of SPMNP 1.0 with dimercaptosuccinic acid (DMSA). Thus, we generated DMSA-SPMNP 2.0 and used DMSA-SPMNP 2.0 to isolate endosomes and lysosome from HeLa cells. Using our SPMNP subcellular fractionation protocol, we are able to isolate high-pure-high-yield lysosomes using DMSA-SPMNP 2.0 for lysosome proteomics and lipidomics in order to better understand subcellular compartments.
