Live cell imaging of HeLa cells: Live cell imaging of HeLa cells stable expressing Cell Cycle-Chromobody (TagRFP). Images from a time series of 22 hours are shown

Cell Cycle-Chromobody signal during the cell cycle: In G1, the Chromobody signal is homogeneously distributed throughout the nucleus and cytoplasm. During S phase it accumulates in the nucleus and visualizes the formation of replication foci. In G2, the foci disappear and the cell divides (mitosis).

The time lapse analysis reveals the reorganization of actin after treatment with Cytochalasin D: HeLa cells were subjected to confocal imaging upon treatment with 2 µM of Cytochalasin D for 1 hour and recovery for 4 hours. Actin Chromobody enables monitoring of actin dynamics in real-time in living cells.

Nuclear Actin-Chromobody: NIH 3T3 cells (murine fibroblasts) transfected with the nuclear Actin-Chromobody (TagGFP2, green) and the Lamin-Chromobody (TagRFP, red) were starved in serum-free medium for 24 hours. Nuclear Actin-Chromobody probed endogenous F-actin assembly and distribution is shown 30 s after stimulation with serum. Courtesy of Matthias Plessner.
