Figure 2From: Low affinity PEGylated hemoglobin from Trematomus bernacchii, a model for hemoglobin-based blood substitutesPEGylation reaction rates. Reaction time dependence of PEG conjugation on globin subunits as determined from the densitometric analysis of SDS-PAGE gels: 0 PEG bound per subunit (open circles), one PEG bound per subunit (open inverted triangles), two PEG bound per subunit (open squares), three PEG bound per subunit (open diamonds), four PEG bound per subunit (open triangles).Back to article page
