Since their introduction some years ago the Nicholson Molecular Models have become the standardised system for many groups working on protein structure, including x-ray crystallographers, chemists and biochemists.

The ease of assembly and low cost have ensured their increasingly widespread use in most biochemistry and medical departments where appreciation of protein and nucleic acid structure is essential. The models meet the need for accurate representation of three dimensional structures by showing the position of each atom, its proportionate Van der Waal's radius and the correct bond angles.
