DISTINCTION BETWEEN GENOTYPES OF LUPINUS SPECIES BY SODIUM DODECYL-SULFATE GEL-ELECTROPHORESIS AND BY CAPILLARY ELECTROPHORESIS

Effective distinction was achieved among a wide range of lupin grain s amples by either sodium dodecyl sulphate (SDS)-gel electrophoresis or capillary electrophoresis, based on grain-protein composition. Capilla ry electrophoresis was faster (< 1 h) and provided slightly greater di stinction between the samples. On the other hand; SDS-gel electrophore sis could provide a greater throughput of samples in a 24 h period. Ei ther technique could be used successfully to distinguish between lupin species and cultivars for taxonomic analysis or seed identification.
