Electrofocalisation en gel d'agarose, application a la determination d'especes de poissons et coquilllages.

The electrophoretic study of sarcoplasmic fraction soluble in water or in low ionic strength solutions can be applied to species identification; in this field isoelectric focusing (IEF) gives excellent results. In this paper thin agarose gels have been used in IEF for the determination of marine species. The preparation of these agarose gels and the running conditions are described. The use of agarose gel in IEF is a relatively new technique, different companies market several different agarose ampholyte systems; these products should be tested to find the most adaptable.
