It has been demonstrated that the affinity of hemoglobin to oxygen in the reindeer Rangifer tarandus decreases with ageing. The value of P50 for hemoglobin of 2-3 month foetuses is equal to 22.0 +/- 0.8 mm Hg, newborn animals--to 24.5 +/- 0.5 and adult ones--to 28.0 +/- 0.5 mm Hg. After dialysis, these values are equal correspondingly to 12.2 +/- 0.5, 19.3 +/- 0.4 and 23.6 +/- 0.6 mm Hg. Therefore foetal hemoglobin exhibits significantly higher oxygen affinity as compared to the adult type.
已经证明，驯鹿（Rangifer tarandus）血红蛋白与氧气的亲和力会随着年龄增长而降低。2 - 3个月大胎儿的血红蛋白P50值等于22.0±0.8毫米汞柱，新生动物为24.5±0.5，成年动物为28.0±0.5毫米汞柱。透析后，这些值分别相应地为12.2±0.5、19.3±0.4和23.6±0.6毫米汞柱。因此，与成年型血红蛋白相比，胎儿血红蛋白表现出明显更高的氧亲和力。
