Electrophoretic studies on muscle myogens of some penaeid prawns

The muscle myogen patterns of some penaeid prawns studied by electrophoresis in cellulose acetate membrane are presented. Each pattern was species specific and appears to be independent of sex. The results suggest that muscle myogen patterns could be useful in taxonomic studies of penaeid prawns. Specimens preserved in phenoxyethanol were compared with fresh specimens. Preservation resulted in some losses of protein zones and, in cases where sufficient zones are preserved, the method could be used to advantage for solving taxonomic problems. Mr. Lim unfortunately passed away in November 1969.
