BCMB/CHEM 8190 ANSWERS PROBLEM SET 9 1) Dissociation constant = 2X10^-4 X 5X10^-6 = 1X10^-9 2) The relative rate of build-up of NOEs will be 300,000/2000. A 20% contribution from the free NOE would occur with a free to bound ratio of X/(X-1) where X*2)/((1- X)*300) = 0.2. Assuming the ligand binding constant is relatively high, 20% would occur at a 30:1 ligand to protein ratio. 3) Iron oxide nano particles exert their greatest effect on T2 – making it shorter.

Unformatted text preview: You would use a T2 enhanced sequence. T2 filters usually result in loss of signal from regions having the shortest T2 – these regions would appear dark. 4) a) dV = 1/( π T2*) + 1/( πτ ) = 0.5 + 1/( πτ ) = 1.0; τ = 0.64s b) dV = 1/( π T2*) + ( τ /(8 π ))(wa-wb)**2 = 0.5 + ( τ /(8 π ))(2 π *100)**2 = 5.0; τ = 2.9x10**(-4)s...
