Abstract:

To investigate the tissue specificity of isozymes from Pelteobagrus fulvidraco, 5 isozymes (MDH, ME, SOD, EST and GD) from 13 tissues (blood, gills, brain, liver, heart, stomach, kidney, gonad, muscle, intestinal, head kidney, spleen, and bladder) of Pelteobagrus fulvidraco were preliminarily studied by using vertical polyacrylamide gel gradient electrophoresis. Isoenzyme bands of MDH in brain, kidney and head kidney was very special respectively. Only one isoenzyme bands of ME was presented in liver. Isoenzyme bands of SOD in brain, liver, intestinal and muscle was very special respectively. The most specific EST was in muscle. Isoenzyme bands of GD in gills and brain was very special respectively. The results showed that the five isozymes presented the tissue specificity to varying degrees.
