0 a protein (= a substance found in food that is necessary for the body to grow) found in milk and cheese, also used to make a type of paint:
Many butter substitutes contain milk derivatives such as whey powder or casein.
The caseins, the major family of milk proteins, are largely unaffected by pasteurization.
Casein can be applied as thin as watercolor or as opaque as gouache, and it dries relatively quickly.
Casein paint has long been available to artists, but its use diminished with the promotion of acrylic painting in the 1950s and 1960s.
The activity blots were performed with 10-20% gradient tricine gels, whereas the zymograms were in 4-16% trisglycine gels containing casein.
However, casein in zymogram gels can affect the migration of proteinases during electrophoresis.
The control diet consisted of a standard laboratory diet containing 23% casein as a source of protein.
Electrophoresis in casein substrate gels demonstrates the presence of 2 distinct proteases in the egg secretions.
