Description from original page:

Microscopy of cells with size scale. P19 mouse embryonal carcinoma cells were fixed with methanol and stained using an antibody that specifically binds the protein α-catenin. The α-catenin protein is concentrated at the cell surface where it functions to anchor cell surface cadherin cell adhesion proteins to the intracellular cytoskeleton. The locations of α-catenin proteins were visualized by scanning laser confocal microscopy. These are average size animal cells. Source: my personal image.
