Figure 2.

Values of PO2 and Hill's cooperativity coefficient at half oxygen saturation (P50 and n50) for the two major isohemoglobin components of (A) eastern and (B) coast moles at 37°C, and their pH dependence in the absence and presence of added Cl- (0.1 M) and 2,3-DPG (DPG/Hb4 ratio > 50). Upper right insets: diagrams of isoelectric focusing column at the end of focusing illustrating the relative abundance of the individual hemoglobin components and their isoelectric points at 5°C.
