Viscosity determination of artificial serum using magnetic field induced magnetic microparticle aggregation. (A) Change in T2 with time for synthetic “myeloma serum” at 0.47 T. T2, i is the initial or starting T2. T2, t is the T2 at some time t. The solutions were: a). FBS + 20% PBS (v/v); b). FBS; c). FBS + 10mg/mL bovine IgG (v/w); d. FBS + 20 mg/mL bovine IgG; e). FBS + 50 mg/mL bovine IgG; and f). FBS + 100 mg/mL bovine IgG. (B) The rate of T2 change from (A) versus the reciprocal of viscosity.
