Figure Lengend Snippet: Determination of circulating halflife and hemodynamic response of di-Hb in vivo ( a ) Circulating halflife was determined in male Sprague-Dawley rats. Top-load doses of protein were administered via intravenous infusion to six rats each in experimental (SGE 953, filled circles) and control (rHb1.1, open circles) groups. Time-dependent curves of plasma hemoglobin concentrations are shown; ( b ) Hemoglobin concentrations in peritoneal lavage fluid at two time points following administration of rHb1.1 (open bars) or dihemoglobin from SGE 953 (filled bars) to separate groups of Balb/C mice; ( c ) Changes in mean arterial pressure following administration of hemoglobins to conscious, unrestrained rats. Top-load doses of rHb1.1 (filled triangles, orange), SGE 953 di-Hb (filled circles, blue), crosslinked SGE 2812 tetra-Hb (filled crosses, green), or HSA (50 mg/mL, filled squares, purple) were administered to separate groups of rats (n = 6 in all groups).
