Proteomic Analysis of Snakehead Fish (Channa striata ... - EJUM

Proteomic analysis of snakehead fish muscle tissue27(1100 Series, Agilent, Germany). Proteins’ functions andcharacteristic information were obtained from both thePubMed (www.ncbi.nlm.nih.gov/entrez) and Swiss Prot(www.expasy.ch/sprot/sprot-top.html).Results and DiscussionSnakehead fish has long been consumed as a sourceof dietary protein. It is also well known traditionally forits medicinal property for healing of wounds. In thisstudy, the proteins extracted from the fish’s muscle tissuewere analyzed. Different sizes of wild type snakeheadfish caught at different seasons were used in the study.The data obtained provide useful information on thenutritional and medicinal properties of snakehead fish.Culturing of snakehead fish has been carried out inMalaysia due to the high demand of the fish. As a largeproportion of fish muscle tissue is made up of proteins,cultured fish muscle tissue texture can be monitored bycomparing their protein profile with those of the wildtype fish.In order to study the protein profile of snakehead fish,fishes of different sizes that were caught at differentseasons were analyzed. Three batches of snakehead fishcaught in November (B1), January (B2) and March (B3),respectively were used in this study. From each batch,eight different lengths of snakehead fish were used, whichwere at 16 cm, 23 cm, 24 cm, 25 cm, 28 cm, 29 cm, 30cm and 38 cm lengths.In B1, it was found that smaller fish (16 cm and 23cm) contained significantly higher protein content(P
