PubMedPubMed 产品介绍This gene is a member of the type II keratin family clustered on the long arm of chromosome 12. Type I and type II keratins heteropolymerize to form intermediate-sized filaments in the cytoplasm of epithelial cells. The product of this gene typically dimerizes with keratin 18 to form an intermediate filament in simple single-layered epithelial cells. This protein plays a role in maintaining cellular structural integrity and also functions in signal transduction and cellular differentiation. Mutations in this gene cause cryptogenic cirrhosis. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]. 靶点与功能
CK8是II型中性细胞角蛋白,分子量约52kDa,常与CK18形成异二聚体,主要表达于单层上皮细胞(如胃肠道、肝脏、胰腺上皮)。其核心功能包括: 结构支撑:维持上皮细胞形态和机械强度,参与细胞迁移和极性建立; 疾病关联:在胆管癌、胰腺癌、乳腺癌等肿瘤中高表达,与肿瘤侵袭转移能力正相关; 临床价值:通过IHC检测可辅助鉴别上皮源性肿瘤与间叶组织肿瘤,是病理诊断的重要标志物。 实验操作关键要点
IHC-P优化(肝组织切片): 抗原修复:采用柠檬酸钠缓冲液(pH6.0) 微波修复20分钟(95℃),增强胞质信号; 阳性定位:肝细胞胞质呈细丝状或弥漫性棕黄色阳性,胆管上皮细胞表达更强; 封闭处理:5% BSA+0.3% Triton X-100室温封闭30分钟,减少非特异性结合。 WB检测注意事项: 样本处理:RIPA裂解液(含1mM PMSF)冰上裂解30分钟,12000g离心取上清;若检测磷酸化CK8,需添加磷酸酶抑制剂(如PhosSTOP); 电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,目标条带约52kDa; 抗体孵育:兔单抗1:2000稀释(5%脱脂奶粉+TBST),4℃孵育过夜,HRP二抗(山羊抗兔)1:5000室温孵育1小时。 公司正在出售的产品
