Protein filament

In biology, a filament is a long chain of proteins, such as those found in hair, muscle, or in flagella.

Protein Filament Media

• 

  Developing wood cells in poplar showing microfilaments (in green) and cell nuclei (in red)

• 

  This is a representation of a microfilament breakdown in a muscle fiber. It shows the different zones and disks within the sarcolemma of this muscle fiber.

• 

  A human cell showing the tubulin component of the cytoskeleton in green and the nucleus in red. The blue staining is a single cytoplasmic protein.

• 

  This helps depict the role that microtubules play in cellular division. In this fluorescent image, the microtubules are highlighted green and can be seen helping to pull the cells apart.

• 

  Human neural stem cells stained for Sox2, in green, and vimentin, in red. Vimentin is a type III intermediate filament (IF) protein.
