👉 In biochemistry, chromotypography is a method used to determine the relative proportions of specific proteins in a sample. It involves identifying the unique features (chromophores) that are present on each protein and then comparing these features using a chromatogram or spectrophotometer to identify the presence of different types of proteins. The term "chromotypography" refers to the process by which proteins are identified as belonging to specific groups based on their unique properties. These properties include their size, shape,
