  • METHOD FOR QUICK DETERMINATION OF CYTOKERATIN 19 (CK19) AND PRIMERS AND PROBES THEREFORE
    Publication number: 20070218496
    Abstract: A method for determination of CK19 mRNA is provided characterized in that a part of CK19 mRNA is amplified using a first primer hybridizing to a region located on a first exon of the CK19 gene and a second primer hybridizing to a region located on a second exon of the CK19 gene locating downstream of the first exon. The amplificate is than detected using two kinds of probes.
