Staining Contrast Structures Components Explain Light Microscopy Works

Staining enhances contrast in light microscopy, making cellular components visible and distinguishable by differential absorption, as they often lack distinct color otherwise.

La tinción aumenta el contraste en la microscopía óptica, haciendo visibles y distinguibles los diferentes componentes celulares que de otro modo serían incoloros, al ser absorbida diferencialmente por diversas estructuras.

Front Explain why staining is useful for light microscopy & how it works.
Back Staining
  • Enhances contrast of the image and lets us highlight certain structures
  • Different components of cell take up stains to different degrees
  • Increase in contrast allows components to be visible clearly
  • Without staining, it would be hard to differentiate between different structures as they usually do not have a distinct color without staining
