A time lapse experiment of Saccharomyces cerevisiae expressing GFP-tagged MCM1. MCM1 is a transcription factor involved in cell-type-specific transcription and pheromone response; plays a central r...

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...

Images of negatively stained chromatin fibers prepared from tandem arrays of a nucleosome positioning sequence reconstituted with purified histones together with the results of Monte Carlo simulations...

Z-series image of mouse ES cells carrying a beta-globin BAC transgene array (clone 8d) and transduced with a lentivirus containing an EGFP-lacI expression cassette. EGFP-LacI binding (green) to the 25...

Z-series image of mouse ES cells carrying an alpha-globin BAC transgene array (clone 7d) transduced with a lentivirus containing an expression cassette for EGFP-LacI. EGFP-LacI binding (green) to the...

Z-series images of mouse ES cells carrying DHFR BAC transgene array (clone 36) and differentiated into fibroblast-like cells. 3D FISH shows increase in number of lac operator foci (green) and change ...
