June 24th - Data Analysis

For the past week or so I have been working on analyzing the data I gathered from ICP-AES. So far I have found two interesting trends: as the PEG percentage increases (so, DNA-DNA spacing decreases), the charge neutralized by hexamminecobalt(III) increases and the charge neutralized by magnesium decreases, and as the magnesium concentration increases, the charge neutralized by magnesium increases and the charge neutralized by hexamminecobalt(III) decreases. These two trends are not surprising, and correlate well with the expectations of the DNA system. What is even more interesting though, is determining the concentration of magnesium needed at each PEG percentage so that hexamminecobalt(III) and magnesium equally charge neutralize the DNA (shown in the graph below).
