  • Loss of sialic acid from apolipoprotein j as an indicator of alcohol intake and/or alcohol related liver damage
    Patent number: 6498038
    Abstract: Disclosed is a method for determining alcohol intake or alcohol induced liver damage in a subject by quantifying the content of sialic acid in apolipoprotein J (Apo J). In particular the present invention involves the steps of (a) providing a sample containing Apo J from a subject; (b) purifying the Apo J from the sample; (c) determining sialylation index, i.e., moles of sialic acid peer mole of Apo J in the sample; and (d) evaluating whether the sialylation index is an indication of alcohol intake or alcohol related liver damage recovery from alcohol addiction or alcohol relapse in the subject.
