further chromatography of both fractions on an immunosorber with monoclonal antibodies to apolipoprotein a-i showed that 1 ) apolipoprotein a-ii only occurs in association with apolipoprotein a-i , 2 ) apolipoprotein a-iv is only present as part of a separate lipoprotein family ( lipoprotein a-iv ) , and 3 ) apolipoprotein e-enriched lipoprotein a-i : a-ii and lipoprotein a-i are the main apolipoprotein a-containing lipoproteins secreted by hepg2 cells .
