About this work
Colour-enhanced transmission electron microscope image of a polymorphonuclear leucocyte or neutrophil. This type of white blood cell has many lobes to its nucleus - four can be seen here in white/yellow. The nuclear membrane is highlighted in purple. Neutrophils are mainly involved in ingesting and destroying small organisms such as bacteria. The cell is approximately 8.9 micrometres in diameter.
