Step-by-Step Protocol for Superparamagnetic Nanoparticle-Based Plasma Membrane Isolation from Eukaryotic Cell
Here, we elaborate our detailed protocol for synthesis, functionalization, and application of superparamagnetic nanoparticle (SPMNP) for plasma membrane and lysosome isolation. We used standard thermal decomposition-based synthesis of iron oxide (Fe3O4) core SPMNP 1.0. Using ligand addition methodology, we surface functionalized SPMNP 1.0 with phospholipids and generated phospholipid-SPMNP 2.0. Further we used NH2-phospholipid-SPMNP 2.0 to isolate plasma membrane. Using our SPMNP subcellular fractionation protocol, we are able to isolate high-pure-high-yield plasma membrane using NH2-phospholipid-SPMNP 2.0. As a future perspective, we propose to use SPMNP on clinical patient samples and perform mass spectrometry-based proteomics, lipidomics, and glycomics for early cancer diagnosis.
