Blotting matrix

A blotting matrix, in molecular biology and genetics, is the substrate onto which macromolecules, such as proteins, are transferred in a blot method.^[1] The matrices are generally chemically modified paper filters or microporous membrane filters. In a dot blot, macromolecules are applied directly to the matrix. Macromolecules can also be separated and transferred via gel electrophoresis.^[1]
