Abstract
OCCURRENCE of multiple hæmoglobins has been reported recently in fish as well as in other vertebrates. In particular, Salmonidæ was found electrophoretically to contain fairly close amounts of two or more components1,2. Some physico-chemical properties of the two components of blood hæmoglobin in the salmon Oncorhynchus keta, which were prepared from hæmolyzate by starch zone electrophoresis, have already been reported3. The fast-migrating component in the physiological pH region (designated component F) was more labile to heat denaturation, less soluble in concentrated salt solution, and behaved less anionically in electrophoresis than another component (designated as component S in view of its slow migration). Their behaviour in column chromatographic and absorption spectra in the Soret region were also more or less different from each other.
