Example Embodiment
[0032] Example 1
[0033] The following is a case of leukemia bone marrow blood sample, total RNA extracted, Ion Torrent sequencing platform, the specific implementation of fusion gene detection.
[0034] The detection principle of this embodiment is that an initial library constructed from genomic DNA or mRNA of a tumor sample is hybridized with a biotin-labeled probe, and the fusion of core genes is captured through the affinity of streptavidin and biotin Gene DNA or RNA fragments, and perform high-throughput sequencing analysis.
[0035] 1. Extraction of total RNA from transcriptome
[0036] Use QIAamp RNA Blood Mini Kit from QIAGEN to extract total RNA from a bone marrow blood sample of patients with acute myeloid leukemia. For details, see the instructions;
[0037] RNA quality control uses the following three standards: (1) Agilent 2100 capillary electrophoresis, RIN> 7.0; (2) NanoDrop spectrophotometer, 260 / A280 value 2.0; (3) Agarose gel electrophoresis, 28S rRNA and 18S rRNA d...
