PubMedPubMed 产品介绍The protein encoded by this gene is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. The type I cytokeratins are clustered in a region of chromosome 17q12-q21.

细胞角蛋白19(Cytokeratin 19, CK19)是I型酸性角蛋白,分子量约40kDa,由KRT19基因编码。其核心功能与研究价值包括: 组织特异性:主要表达于单层上皮细胞(如乳腺导管、胆管、肺泡上皮),是上皮细胞分化的关键标志物; 肿瘤诊断:在腺癌(如乳腺癌、肺癌、胰腺癌)中高表达,阳性率>85%,与CK7联合检测可提高诊断特异性; 临床应用:循环肿瘤细胞(CTC)检测的重要标志物(如CellSearch系统),可用于癌症转移监测和预后评估。 实验操作关键要点
IHC-P腺癌诊断(乳腺癌样本): 抗原修复:柠檬酸钠缓冲液(pH6.0)微波修复20分钟(95℃),冷却后用3% H₂O₂封闭10分钟; 阳性定位:肿瘤细胞胞质呈弥漫性棕黄色阳性,腺管结构周边细胞表达更强; 对照设置:必须包含正常乳腺组织(阳性对照)和鳞癌组织(阴性对照)。 WB验证(细胞裂解液): 样本处理:使用含1mM PMSF的RIPA裂解液冰上裂解30分钟,12000g离心15分钟取上清; 电泳条件:12% SDS-PAGE凝胶(分离小分子量蛋白),恒压80V浓缩胶、120V分离胶,转膜用0.45μm PVDF膜(200mA恒流1小时); 抗体稀释:一抗1:1000稀释(5% BSA+TBST),4℃孵育过夜,HRP二抗1:5000室温孵育1小时,曝光时间15-30秒。 公司正在出售的产品
