You are trying to establish the IgG response from a recentlyvaccinated individual, where it will be important to know how muchIgG they have both before and after the vaccination. You start withtwo samples of 8 mL of blood, one from before vaccination and oneafter. You use an affinity chromatography technique to remove justthe IgG (Îµ = 1.35 g-1L cm-1). You end with a 2 mL sample of each.The pre-vaccinated sample has an A280 reading of 0.85, and thepost-vaccinated sample has an A280 reading of 0.202 with a 10-folddilution (both with a 1 cm path length).
a) How many micrograms of IgG were in each of theoriginal blood samples?
b) What fold change in IgG amounts was seen aftervaccination?
