CH5424802 is a potent and selective ALK inhibitor.
Anaplastic lymphoma kinase (ALK) is a tyrosine kinase that is constitutively activated in certain cancers. .
In vitro: In cell free assays the IC50 of CH5424802 for enzyme activity of ALK was 1.9 nM; the dissociation constant (KD) value for ALK in an ATP-competitive manner was 2.4 nM. The inhibitory activity for two hot spot-activating mutations (F1174L and R1275Q) in neuroblastoma was comparable to that for wildtype ALK [1].
In vivo: In the NCI-H2228 model, oral administration of CH5424802 resulted in dose-dependent tumor growth inhibition (ED50 = 0.46 mg/kg) and tumor regression. Moreover, treatment of 20 mg/kg CH5424802 showed rapid tumor regression and tumor regrowth did not occur throughout the 4-week drug-free period [2].
Clinical trial: No clinical data are available currently.

从GEO和ARRAYEXPRESS下载了miRNA的表达数据矩阵，但是结果不太一样，大致两种：①数值从个位数到几万不等，而且没有小数点；②数值在10上下，有小数点。见图
请问怎么知道数据是否经过了log转换？有注释文件说明吗？还是直接判断①是没转换的，②是转换的？

研究蛋白质芯片的意义
1。蛋白质是基因表达的最终产物,接近生命活动的物质层面；
2。探针蛋白特异性高、亲和力强,可简化样品前处理，甚至可直接利用生物材料(血样、尿样、细胞及组织等)进行检测；
3。适合高通量筛选与靶蛋白作用的化合物；
4。有助于了解药物或毒物与其效应相关蛋白质的相互作用。
蛋白质芯片的分类：
1.蛋白质检测芯片
2.蛋白质功能芯片
蛋白质芯片的制备：
1。固相载体及其处理
载体（滴定板、滤膜、凝胶、载玻片）
2。蛋白质的预处理
选择具有较高纯度和完好生物活性的蛋白进行溶解
3。点制微阵列
可使用点制基因微阵列的商品化点样仪或喷墨法等
4。膜为载体：芯片放入湿盒，37°C1h
载玻片为载体：化学修饰产生醛基固定蛋白
5。微阵列的封闭固定微阵列上的蛋白样点
主要封闭试剂：BSA或Gly

请问，我通过基因芯片筛选差异基因，有上调的也有下调的，即FC有正值，亦有负值，那么负值怎么取log？谢谢
1、一张芯片上可以同时分析成百上千的探针，这样的情况可以检测多少位点？
2、基因芯片技术通量会有多大？怎么计算？
求助各位大神，点击Downloadfulltable无法下载，总是出现错误，已经排除网络的问题，不知道是否还有其他方法下载，上面有一个Datatable的表格，不知道是不是芯片平台文件？
中唐临界风险，33岁，第一胎，然后羊水穿刺加CMA基因芯片检查，染色体核型正常，4维彩超正常，医生说发育速度偏慢，但还算正常范围，CMA结果异常，如照片
做蛋白质和microRNA的关系，那么先找出差异的蛋白质还是找出差异的microRNA好呢？有没有做ITRAQ和MICRORNA芯片好的公司推荐，非常感谢！
