Hemoglobins and serum proteins of four species of pinnipeds have
been analysed by starch-/agar-gel electrophoresis at pH 9.0, the serum
proteins also by agar-gel electrophoresis at pH 6.3.
The original purpose of the work was to discover polymorph characteristics
to be used in population studies of the two most valuable
species: the harp seal and the hooded seal. During sampling also some
specimens from ringed and bearded seals have been collected, and
descriptions of the obtained electrophoreograms are given. The greatest
attention has been paid to intraspecific variations detectable by these
relatively simple electrophoretic methods.
For all species, several individual differences have been found.
Particularly the transferrin variations in harp and ringed seals (probable
transferrins) and haptoglobin variations in the hooded seal are
conspicuous.
Individual differences in other serum proteins have been found for
all species, but they are most obvious in the hooded seal. Although no
definite proof can yet be offered (except for the transferrins of the harp
seal), it is probable that most of the variations are genetically controlled.
The transferrins of harp seals, proteins labelled II and III of hooded
seals, and perhaps also the haptoglobins of the hooded seal seem to be
suitable characteristics for studies of population problems.
