文献速递：全面液体分析循环肿瘤DNA和蛋白质生物标志物为评估预后带来新的可能

，并且可以与其他策略相结合，提供更好的评估。 其中，为了验证ctDNA动态与HCC进展中的肿瘤负荷相关性，该研究团队提取并分析了患者在临床过程中收集的连续血浆样本中的ctDNA。采用了QIAamp Circulating Nucleic Acid Kit+ QIAseq cfDNA All-in-One Kit进行血浆游离DNA提取与文库构建，并结合全基因组测序与靶向测序技术来获得突变等位基因频率的相关性（图A）。 图A. HCC进展过程中血浆样本中体细胞SNVs和CNVs的动态变化。在患者H1607的临床

On-chip Isotachophoresis for Separation of Ions and Purification of Nucleic Acids

with a fluorescent reporter (e.g. AF488, SYBR Green II), the overall fluorescence intensity can be integrated and compared against a calibration curve to obtain quantitative concentration information.12 Additionally, in nucleic acid extraction experiments, sample

DNA/RNA/Protein Purification from Cultured Cells Using SQ DNA/RNA/Protein Cell Kit (1-2 x 106 cells)

. For Total Nucleic acid isolation, proceed step 8-12. For RNA and DNA isolation, proceed step 13-25. Total Nucleic acid Isolation: 8. Add equal volume (400 μL) of isopropanol. Mix throughly by vortexing for 30 seconds. Incubate the tube at room
