The shift in formal potential reveals the mode of interaction between drug and DNA.
The electrochemical properties of organic dyes are very well known for the solution phase; they represent the formal potential, E[degrees] , between 0.08 and -0.25 V (versus SCE), very close to those redox reactions of several enzymes over a large pH range.
Figure 7 shows the formal potential of Hb, immobilized onto the CdO-NPs/ carbon paste electrode; in PBS has a strong dependence on the pH of solution.
He goes straight to the point, overturning ceramic convention, pulling, molding, and refashioning, his unfumbling hand bringing about maximum formal potential with minimal means.
The developments along rue de Pommard, where Jean-Pierre Buffi and others created a sequence of small courts and little streets leading down to the new urban park along the river, are some of the most sophisticated pieces of European urban housing built in the last decade (AR June 1995): they self-consciously draw on the traditions of Paris, while using up-to-date constructional techniques, and the spatial and formal potential these offer.
Style is important as the vehicle for, and governing instance of, the expansion, diversification and combination of independently steered streams of formal potential. The progressive accretion, from work to work, of that form of aura which only long-term evolution can provide will be the most effective guarantee for the proper exploitation of such possibilities, no matter what surface characteristics an individual composer's style may display.
The myoglobin showed quasireversible electrochemical behavior with a formal potential of -48 mV (vs Ag/AgCl), cathodic and anodic peaks were not observed using the bare graphite electrode.
Nicodemus points out that by the early 20th century, cultural exchange between Africa and Europe was a two-way process; that as European artists were exploring the formal potential opened up by African art, African artists were experimenting with European-style easel painting and figurative representation.
The mode of NPF-DNA interaction can be judged from the variation in formal potential. In general the positive shift (anodic shift) in formal potential is caused by the intercalation of the drug into the double helical structure of DNA [26], while negative shift is observed for the electrostatic interaction of the cationic drug with the anionic phosphate of DNA backbone [27].
In fact, Olivier's deployment of the language of abstraction is based largely on her appropriation of minimalistic bands and grids, and post-Minimalist strategies, from which she creates works that emphasize abstraction's emotive rather than formal potential. The vertical drips of Screen Memory #1, and the grid in Screen Memory #2, both function to create a bridge between color and darkness, as if figuring the power of subjective perception.
Ebdeg and Efdeg are the formal potentials of the free and bound forms of drug respectively.
