Blue Native PAGE co-fractionation of purified human endosomes

EndoMAP aims to systematically dissect the human endosomal protein complexes. To purify endosomes from human cells, a modified Endo-IP protocol was developed to be compatible with complexomics methodologies and evaluated by DIA-MS. Three independent biological replicates of human endosomes purified by the modified Endo-IP protocol were subjected to Blue Native PolyAcrylamide Gel Electrophoresis (BN-PAGE) co-fractionation to identify possible protein complexes based on correlation profiling.
