Obtained enormous global visibility and tremendous response from the authors and readers from all over the world inspired the publisher to maintain reputed Open Access Journals in various scientific disciplines. The journals have over 15 million readers and the reputation and success earned can be attributed to the strong Editorial Board which contains over 50, eminent personalities that ensure a rapid, qualitative and quick review process.
The preparation of such samples remains an empirical endeavour, more art than science. Nonetheless, decades of experience have yielded a large body of practical strategies and techniques towards this end. Such efforts with protein—DNA complexes enjoy special advantages, but also involve control of a larger set of variables.
High purity, chemical and conformational, preparations of both macromolecules are important. Modern crystallisation screens, which encapsulate the accumulated wisdom of prior investigations, serve as an excellent starting point for experimentation.
Preparation of crystalline specimens requires highly concentrated solutions of the molecules of interest. Success is favoured when high chemical and conformational purity has been achieved. Extensive experience in preparation of protein crystals can be applied to growth of protein—DNA crystals.
Additionally, the length, composition, and identity of the termini of the DNA molecule play significant roles in crystallisation.
Initial crystallisation trials are set up using a concentrated stock of protein—DNA complex of interest with premade formulations that sparsely sample crystallisation space.
Precipitation and crystal formation under these conditions are used to direct efforts for further crystallisation experiments. A large number of crystal screens are now commercially available, including those designed for crystallisation of protein—nucleic acid complexes.
New formulations are then prepared based on the conditions that result in the hits and used for reproduction and optimisation of the crystals. Acta Crystallographica Section D: Journal of Molecular Biology Methods in Molecular Biology Chait BT Mass spectrometry in the postgenomic era.

Protein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms.
Protein purification is vital for the characterization of the function, structure and interactions of the protein of interest.
