[0031] Step 1. Take a patient's cancer tissue and blood samples to extract DNA. The kits used are TIANGENTGuide Cells / Tissue Genomic DNA Kit and TIANGENT TGuide Large Volume BloodGenomic DNA Kit (1-3ml).
[0032] Step 2, DNA sample library preparation. First use the Bioruptor UCD-300 non-contact automatic ultrasonic breaker to randomly interrupt the DNA, ctDNA does not need this step. Take 400ng of DNA, dilute it to 50μl with nuclease-free water, transfer it to a 0.5mL Eppendorf LoBind Tube, mix well, centrifuge briefly and put it on ice for use. Place the sample: Place the centrifuge tubes symmetrically (if there is a single tube, add water to the empty tube to balance), tighten the rotor, place it on the ice box, and pre-cool for 1-2 minutes. 150-200bp ultrasonic break. Repeat the previous step of ultrasonic crushing, a total of 9 cycles, and end in about 90 minutes. The library was then prepared using the KAPA library construction kit.
[0033] Step 3, RNA probe prepara...
