"Oxygen dissociation curves were obtained spectrophotometrically
by the tonometric method." |
| Comments |
"Buffalo Hb are characterized by a very-low O2 affinity,
even in the absence of organic phosphates such as GriP2.
Under these conditions at pH 7.4 and 20°C (in 0.1 M Hepes
plus 0.1 M NaCl), P50 is 7.1 mmHg, a value almost identical
to that of human hemoglobin fully saturated with its physiological
effector (GriP2)." |
