Evidence of a Second Fœtal Hæmoglobin in the Newborn Goat

Abstract

RECENTLY, some reports have appeared suggesting the existence of an embryonic human hæmoglobin which shows slight differences as compared with the fœtal hæmoglobin of the newborn child. Using an alkali denaturation technique, Drescher and Künzer¹ and Allison², for example, obtained evidence that the hæmoglobin present in early fœtal life is different from the fœtal and adult hæmoglobin types. Recent investigations of Halbrecht and Klibanski³ have shown the existence of an embryonic human hæmoglobin which migrates more slowly in paper electrophoresis than the fœtal hæmoglobin from the cord blood of a newborn child. Studying the problem of fœtal hæmoglobin in newborn goats we obtained evidence that in this animal also two different fœtal hæmoglobins occur, which, however, are still present after birth.
