    Real-time PCR
    A type of nucleic acid amplification method based on the basic principle of PCR, which uses oligonucleotides that emit fluorescence upon decomposition to quantify target nucleic acids in real time by checking the fluorescent signal at each PCR cycle. A measurement method that enables.

COMMENT


This test is intended to assist in the selection of therapeutic drugs for colonic and rectal cancer.
This test analyzes DNA methylation using pathological materials. We cannot accept requests of anything other than pathological materials.
A tumor cell content of 20% or more is required for this test. For specimens with less than 20% tumor cells, the results may be undeterminable or lead to false-negative outcomes.
Please refer to the notes below regarding the submission of unstained specimen slides.
Please avoid duplicate requests with other items. If a sufficient amount of residual DNA from 「05755 8: RAS/BRAF gene mutation analysis」 is stored, additional testing can be performed. Please note that if the submitted specimen contains less than 20% tumor cells, the result may be undeterminable or false-negative.

●Submission conditions
For unstained specimen slides, please ensure that histopathological evaluation has been performed and that the tumor cell content (percentage of tumor cells among all cells on the slide) is equal to or greater than the required amount for testing. If the tumor cell content is below the required percentage, please mark the tumor cell area on the back of the unstained specimen slide. Please note that if the slide is submitted without marking, macrodissection cannot be performed, which may affect the test results, including the possibility of false-negative findings.

●About the unstained slides
Please immediately fix the collected tissue by immersing it in 10% neutral buffered formalin, with a recommended fixation time of 6 to 48 hours. When submitting, please prepare consecutive sections of the specified thickness from formalin-fixed paraffin-embedded (FFPE) blocks made within the past three years, whenever possible. Please take sufficient care to prevent contamination during sectioning, such as changing the microtome blade for each specimen. Please note that nucleic acids are fragmented due to formalin fixation of the tissue, and depending on the type and composition of the fixative, fixation time, and storage conditions after fixation, analysis may not be possible.

●About biopsy specimens
Please note that biopsy specimens often have only small amount of tissue, and there is a possibility that the tissue has been mostly depleted or that the fragments do not contain tumor cells.
