This antibody recognizes human Apo C-I in plasma and lipoproteins. Does not cross-react with plasma Apo A-I, Apo A-II, Apo B-100, Apo C-II, Apo C-III and Apo-E.
Apolipoprotein (apo) C-I gene is expressed primarily in the liver, and it is activated when monocytes differentiate into macrophages. A copy of the apo C-I gene, apo C-I', is located 4 kb downstream in the same orientation, on the same chromosome. However, apo C-I' gene has no detectable mRNA product in any tissue, suggesting that it may be a pseudogene. The ap °C-I gene is 4653 bases long and the apo C-I' is 4387 base pairs, and each contains four exons and 3 introns. The differences between the two genes includes a change of the codon for Gln-2 of the signal peptide region of apo C-I', which introduces a translation stop signal. A major difference between the two sequences is also found in the second and third introns of the ap °C-I' gene, which contains 7.5 instead of 9 copies of Alu family sequences.Synonyms: Apo-CI, Ap °C-I, Ap °C1, Apolipoprotein C-I, Apolipoprotein C1
