Melanin
Melanin is a ubiquitous and prominent pigment responsible for color of skin, hair and eyes. Melanin is classified into eumelanin and pheomelanin. Eumelanin is black to dark brown pigment and is present in black hair and retina of the eye. Pheomelanin is yellow to reddish brown pigment present is red hair and red feathers. Melanins are high molecular weight pigments synthesised from phenolic or indolic precursors and is widely present in animals, plants and microorganisms.
- Melanin from Sepia officinalis has been used as a natural pigment for Raman spectroscopy measurements
- In competitive enzyme linked immunosorbent assay (ELISA) for the characterisation of phage antibodies
- As an external standard for spectrophotometrically determining the melanin production in B16F10 cells
