title: Primary structure of ovine apolipoprotein C-II and the production of antibodies directed towards a synthetic fragment (residues 46-59).
abstract: Two distinct activator proteins for lipoprotein lipase were isolated from ovine plasma and purified to homogeneity by reverse phase HPLC. The two proteins were partially sequenced (up to residue 59) and the results show that they are identical except that 6 residues were missing from the N-terminal of the smaller protein. The complete sequence of the proteins has been deduced from amino acid composition studies and by comparison with the sequence information available from other species. Antibodies were produced in BALB/c mice to a synthetic peptide corresponding to a highly hydrophilic region (residues 46-59) of the activator protein. The antibodies cross-reacted with the two forms of activator and with ovine lipoproteins. This work with a synthetic fragment of ovine activator protein confirms that the technique is useful for investigating antibody production and specificity directed against native lipoproteins.
