DIRECTIONS FOR USE Use strictly according to the manufacturers directions
Bacteriostatic Water: Contains preservatives to inhibit microbial growth Used to dissolve and dilute model peptides Has less chance of contamination than sterile water Sterile Water: Does not contain preservatives Used to dissolve peptides, but not recommended for long-term storage or dilution of model peptides More prone to contamination than bacteriostatic water Ultimately, it is up to the users preferences when deciding between these two liquids for peptide reconstitution

In any case, the structure of the Co II -bound NiCo riboswitch reveals four Co II binding sites that likely nucleate formation of a four-way junction stabilized by a network of contacts that may explain how cooperative binding of Co II ions to adjacent sites might be achieved (Figure 22D)
