pubmed:abstractText |
Two forms of intestinal alkaline phosphatase have been recognized in humans. They are very similar in a number of biochemical and immunologic characteristics, but the exact genetic relationship between them remains unclear. To further study this problem, six monoclonal antibodies and a polyclonal rabbit antiserum to human fetal intestinal alkaline phosphatase have been produced. All of the monoclonal antibodies and the rabbit antiserum crossreact with adult intestinal alkaline phosphatase and with the intestinal-like alkaline phosphatase found in D98/AH-2 human tissue-culture cells. Four of the monoclonal antibodies and the rabbit antiserum crossreact with placental alkaline phosphatase, while none of the antibodies or the antiserum recognize liver or kidney alkaline phosphatase. Four of the monoclonal antibodies can distinguish between adult and fetal intestinal alkaline phosphatase in electrophoretic titration-binding studies, with the relative binding of adult enzyme being significantly greater than that of the fetal enzyme in each case. One of these antibodies, which also reacts with placental alkaline phosphatase, can distinguish the type 3 allelic variant of the placental enzyme from types 1 and 2. This indicates that the antibody detects a structural difference in the protein moiety of one of the allelic forms of the enzyme. These data suggest that adult and fetal intestinal alkaline phosphatases represent structurally distinct proteins, either encoded for by different genes or produced by differential processing of a common precursor molecule determined by a single gene.
