PubMedPubMed 产品介绍IRF1 encodes interferon regulatory factor 1, a member of the interferon regulatory transcription factor (IRF) family. IRF1 serves as an activator of interferons alpha and beta transcription, and in mouse it has been shown to be required for double-stranded RNA induction of these genes. IRF1 also functions as a transcription activator of genes induced by interferons alpha, beta, and gamma. Further, IRF1 has been shown to play roles in regulating apoptosis and tumor-suppressoion. 靶点与功能
HNF1α是同源盒转录因子家族成员,分子量约67kDa,主要表达于肝脏、肾脏及胰腺β细胞,通过结合靶基因启动子的“TAATNCAT”序列,调控白蛋白、葡萄糖转运蛋白(GLUT2)、肝酶(如PEPCK) 等关键基因的表达。其突变或表达异常与** maturity-onset diabetes of the young type 3(MODY3)、肝腺瘤、慢性肝病**密切相关,是代谢疾病和肝脏疾病研究的重要标志物。 实验操作关键要点
WB核蛋白检测: 样本制备:使用核蛋白提取试剂盒,提取肝脏或胰腺组织核蛋白,避免胞质污染(内参选用Lamin B1); 电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,转膜选用0.45μm PVDF膜(250mA恒流2小时); 抗体孵育:多克隆抗体1:1000稀释(5% BSA+TBST),4℃孵育过夜,HRP二抗(山羊抗兔)1:5000室温孵育1小时,曝光时间45-60秒。 IHC-P肝组织染色: 抗原修复:采用EDTA缓冲液(pH9.0) 高压修复3分钟(针对福尔马林固定石蜡切片),增强核信号; 阳性定位:细胞核呈棕黄色颗粒状阳性,肝细胞、肾小管上皮细胞高表达; 对照设置:需包含HNF1α敲除小鼠肝组织(阴性对照)和正常肝组织(阳性对照)。 ChIP实验注意事项: 超声条件:将染色质打断为200-500bp片段(功率30%,超声20秒×15次); 抗体用量:5μg抗体/1×10⁶肝细胞,4℃旋转孵育6小时,Protein A/G磁珠富集DNA; 阳性对照:检测已知HNF1α靶基因(如ALB、GLUT2)的启动子区域。 公司正在出售的产品
