The AdnaTest uses a two-step process (Select and Detect) to generate results within 5 hours (see figures “ AdnaTest workflow”). AdnaTest ColonCancerSelect enables the immunomagnetic enrichment of tumor cells from whole blood via epithelial- and tumor-associated antigens. Antibodies against epithelial- and tumor-associated antigens are conjugated to magnetic beads for labeling of tumor cells. Labeled cells are extracted by a magnetic particle concentrator (AdnaMag-L and AdnaMag-S), lysed and mRNA is then purified from these lysates (see figures “ AdnaTest Select – Immunomagnetic cell selection with multiple tumor-associated antibodies labeled to magnetic beads.”). In the second step, the isolated mRNA is transcribed into cDNA and can be amplified using multiplex PCR (see figures “ AdnaTest Detect – Multiplex PCR of various cancer-associated tumor markers”). AdnaTest ColonCancerDetect contains Oligo (dT) 25-coated beads for the isolation of mRNA from the lysate of pre-enriched tumor cells. Reverse transcription results in cDNA that can subsequently be used as template for tumor cell detection and characterization by multiplex PCR. Multiplex PCR provides tumor-associated gene expression profiles for a variety of relevant tumor markers to ensure that the selected cells are cancer cells. The PrimerMix ColonDetect allows amplification of 3 tumor-associated genes and 1 control gene (see table below). The primers generate fragments of the following sizes:
Target gene | PCR Fragment Size (bp) |
GA733-2 | 383 |
CEA | 231 |
EGFR | 163 |
Actin (internal PCR control) | 120 |
Importantly, the AdnaTest is an open platform that allows the profiling of additional custom selected mRNA targets for comphrehensive biomarker discovery.
AdnaTest ColonCancerSelect enables the immunomagnetic enrichment of tumor cells via epithelial and tumor associated antigens. Antibodies against epithelial and tumor associated antigens are conjugated to magnetic beads for labeling of tumor cells in peripheral blood. Labeled cells are extracted by a magnetic particle concentrator (AdnaMag-L and AdnaMag-S) and are subsequently lysed. The results of the AdnaTest are generate within 8 hours.
