SPMNP based Subcellular fractionation: a FluorLipid-SPMNP incubated with HeLa cells for pulse 15 min and chase 240 min; b FluorDMSA-SPMNP incubated with HeLa cells for pulse 15 min and chase 240 min; c Western blot analysis for EEA1—early endosomes and Na⁺K⁺ATPase—plasma membrane marker for NH₂-Lipid-SPMNP incubated with HeLa cells for pulse 15 min and chase 0, 15 and 30 min; d Western blot analysis for early endosomes and plasma membrane marker for DMSA-SPMNP incubated with HeLa cells for pulse 15 min and chase 240 min. Red Label represents the enrichment of EEA1 which is a marker for early endosomes
