产品介绍
结构蛋白（Structural Proteins）
CK-19细胞角蛋白-19(又称CYFRa21-1)主要用于肿瘤方面的研究，近年来大多用于消化系统恶性肿瘤的鉴别，有学者认为：CK-19在胰腺干细胞分化过程中有细胞角蛋白19的表达，把细胞角蛋白19作为胰腺干细胞的标志物。阳性部位：主要在胞浆。
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.
