(a) SDS-PAGE of retrieved intracellular protein following incubation of the cells with EMD–FITC containing no 5 kDa protein. Although no 5 kDa protein was applied to the cells, material at this molecular weight still accumulated with time presumably due to intracellular degradation of a larger precursor (e.g. the 20 kDa protein). (b) SDS-PAGE of retrieved intracellular proteins following incubation of the cells with FITC labelled 5 kDa EMD fraction. No uptake was detected.
