Apolipoprotein was purified from delipidated HDL by gel filtration on a Toyopearl HW-55F column in the presence of urea. Two main apolipoproteins, designated as apo-A I and apo-A II, were obtained. Apo-A I was purified as a single protein with a molecular weight of 28,000. Apo-A II had a molecular weight of 14,000 and its purity was over 90%. Synthesis and secretion of apolipoprotein of HDL by using ^{14}C-leucine was studied with cultured eel-hepatocytes. It was demonstrated that cultured eel-hepatocytes synthesized and secreted both apo-A I and apo-A II. We found that cells cultured for 9 days secreted more proteins among cells cultured for 12 days.}, pages = {25--33}, title = {Apolipoprotein of High Density Lipoprotein of Eel Serum}, volume = {37}, year = {} }
