Aggregation of RBC suspended in autologous plasma measured using a Myrenne aggregometer. Aggregation indices are M at stasis (A) and M1 at 3 s−1 (B) normalized to control (i.e., buffer added without polymer) and presented as mean ± SD for CA(PEG)4 at different concentrations (1.3, 4.0 and 6.7 mg/mL) and linear PEG at a concentration of 6.7 mg/mL. Values for M and M1 < 1 indicate inhibition of RBC aggregation. Measurements were in duplicates for each donor (n = 3). Results demonstrate that at concentrations of 4.0 and 6.7 mg/mL, star-shaped CA(PEG)4 are able to reduce RBC aggregation (p < 0.01).
