General description

Melanin is a distinctive class of pigment found in animals, plants, bacteria, and fungi. It is an amorphous polymer formed by the polymerization of phenolic and indolic compounds.

Application

Melanin has been used:
  • to incubate normal human keratinocytes for Masson-Fontana staining
  • as a standard in the determination of melanin content in normal human epidermal melanocytes and immortalized human keratinocytes
  • as an absorber to mimic human skin or melanocytic nevi and melanoma

Biochem/physiol Actions

Melanin plays a role in camouflage and energy harvesting. It also helps in protection against ionizing UV radiations, protection against biotic factors such as host defense against pathogens, and abiotic factors like heat, cold and osmotic stress. Melanin acts as a potent cation chelator and is a component of several photoprotective creams as it facilitates free radical scavenging activity. Melanin may be useful as a photo protectant in cell culture.

Preparation Note

Prepared by oxidation of tyrosine with hydrogen peroxide.

Questions

1–2 of 2 Questions  
  1. Is there any pretreatment other than sonication that should be done before adding to cells? Also, please let me know if there are any precedents for such processing.

    1 answer
    1. Unfortunately, we do not test any of our products such as M0418 for specific applications. We sell products in small scale for laboratory use and application. The information is based on that Melanin as a small molecule used in Cell culture application. We do not have specific publications or protocols to share.

      Helpful?

  2. I wonder if you can let me know what type of melanin pigment this reagent has. Is it pheo-, eu- or mixed melanin? What is the level of polymerization? Thank you!

    1 answer
    1. This product is synthetic melanin, per Med. Res. Reviews 8 (1988) pp. 525-556, synthetic melanins are "eumelanin type pigments". Unfortunately, no additional information on the level of polymerization is available.
