1Raybiotech G6/G7芯片检测结果。疾病及两个对照组血清样本共12个。首先对样本蛋白浓度的结果使用SAM分析方法,然后进行聚类分析。聚类图显示SCLC,炎症和正常样本明显分离。
The results of Raybiotech G6/G7 Microarrays detection. A total of 12 serum samples were separated into a disease set and two control sets. The results of signaling protein concentrations were analyzed with SAM method initially, and this was followed by cluster analysis. Cluster diagram shows the SCLC, inflammation and normal samples are significantly separated. SCLC: small cell lung cancer.
