Comparison with Idotea balthica basteri BT AF CHARFI, C AS 1:; FF 1:; UR https://archimer.ifremer.fr/doc/1987/acte-1401.pdf LA French DT Proceedings paper DE ;Idotea balthica basteri;Idotea chelipes;Malacostraca;Comparative studies;Haemocyanins;Proteins AB Electrophoregrams of proteins on polyacrylamid gel concentrated at 2.5 - 15% made it possible to separate 24 protein fractions in polytypic Idotea chelipes species, 4 of which having a higher activity and corresponding to hemocyanin. A clear resemblance is evident in proteinograms of various sub-species and in I. chelipes populations whereas those of I. b. basteri seem to be quite different. A variation also exists between sexes within the same population. It corresponds to the slowest fraction whose activity is more intense with females. PY 1987 PD JUL CT Actes de colloques. Ifremer.
