Fig. 1. PMPs are rapidly targeted to peroxisomes. Normal human fibroblasts were microinjected with DNA constructs expressing Pex2p-GFP (A,B), Pex3p-GFP (C,D), Pex16p-GFP (E,F) and GFP-PMP70 (G,H). After 90 minutes, cells were fixed and processed for double indirect immunoflourescence with antibodies to GFP (A,C,E,G) and ALDP (B,D,F,H).
