Lyso-IP is a method that allows for the isolation of lysosomes for proteomics and metabolomics (dx.doi.org/10.17504/protocols.io.bybjpskn; dx.doi.org/10.17504/protocols.io.bx9hpr36). We have developed an analogous approach for purification of early/sorting endosomes (Endo-IP). In addition, we have found that endolysosomal purification via Lyso-IP and Endo-IP can be coupled with a quantitative proteomics workflow to obtain snapshots of Amyloid Precursor Protein (APP) processing to its Aβ products (Park et al. in submission). Here, we describe methods for cell line construction and maintenance of 293 cells with TMEM192-3xHA and 3xFLAG-EEA1, which are used for lysosome and endosome purification, respectively, with the addition of patient mutations to APP promotes processing. Cells with endogenously tagged TMEM192 and stably expressing FLAG-EEA1 are referred to as 293EL cells, for Endo-IP and Lyso-IP. These cells were also prepared in a form that has a deletion of the APP gene (293EL;APP-/-) and the same cells reconstituted with a lentivirus stably expressing APPSw;T700N to allow functional analysis of APP processing.
