Ema localizes to endosomes. Third instar larval garland cells expressing Ema-GFP fusion protein with endosomes labeled with a 5-min pulse of the fluid-phase endocytic tracer avidin-Cy3 followed by an ...

Living Lilium pollen tube labeled with paclitaxel (blue) to mark microtubules (blue) and cytochalasin D TMR to mark endoplasmic reticulum (green) imaged using laser scanning focal microscopy. The grow...

Living Lilium pollen tube labeled with TMRE (red)to mark mitochondria and imaged using laser scanning focal microscopy. Shown is a central 1.0 micron thick x-y slice. The growing tip is devoid of mit...

Living Lilium pollen tube labeled with carboxy-dichlorofluorofluorescein (green) to mark the vacuole and cytochalasin D TMR to mark endoplasmic reticulum (red) imaged using laser scanning focal micros...

Mouse myoblasts stably transfected with GFP-PCNA to label replication foci and the 3D distribution of the GFP signal recorded over time using a confocal microscope. The time series illustrates the dyn...

Shown is a 0.5 micrometer thick confocal image of a midplane section of a 3T3 fibroblast pulsed for 5 min with BrdU and immuno-labeled with anti-BrdU antibodies. Replication is confined to discrete si...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for DNA ligase. DNA was localized using Hoec...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for the DNA methylase Dnmt1. DNA was localiz...

Mouse myoblast cells were transfected with GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, pulsed with BrdU, fixed, and immunostained with anti-BrdU. The image sh...

Phosphorylated H2AX occurs preferentially in open chromatin. Wildtype mouse embryo fibroblasts were treated with the radiomimetic drug neocarzinostatin (NCS) for 1hour prior to being fixed and immunol...
