Immunofluorescence image of Human Embryonic Stem cells stained with an antibody to the active form of Bax (red) and Hoechst (blue). The distribution of Bax, an apoptosis mediator indicates that it res...

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...

Maximum projection of a multipanel, tiled image through the CA region of the hippocampus of adult rat, immunostained to reveal dendrites of neurons (red), astroglia (green) and all nuclei (blue). This...

Z-stack through the CA region of the hippocampus of adult rat, immunostained to reveal dendrites of neurons (red), astroglia (green) and all nuclei (blue). This kind of approach can reveal the spatial...
