Figure Lengend Snippet: Figure 6. The precise localization of DZIP1L in human RPE cells. Spatial localization of DZIP1L was examined using a combination of Ultrastructure expansion microscopy (ExM) and confocal microscopy. As our DZIP1L polyclonal antibody is derived from rabbits, and most of our antibodies for TF and TZ markers are also polyclonal antibodies from rabbit, co-labeling them with antibodies is not feasible. To assess their co-localization, we employed transgenic FLAG-DZIP1L and utilized a mouse monoclonal FLAG antibody (IgG1 isotype) to label DZIP1L. While cilia were marked using anti-Ac-tubulin, a mouse monoclonal antibody with IgG2b isotype. A) FLAG-DZIP1L was localized beneath the classical TZ component CEP290 in both ciliated and non-
