产品描述：人着丝粒蛋白K(CENPK)酶联免疫试剂盒为双抗夹心法ELISA试剂盒，定量检测血清、血浆、组织匀浆、细胞裂解物样本中的CENPK含量。CENPK（着丝粒蛋白K）是一种与着丝粒复合体相关的亚基，其功能是将CENPA蛋白靶向到着丝粒，对于着丝粒功能和有丝分裂进程至关重要。研究显示，CENPK基因在肝细胞癌中异常高表达，其启动子区域的DNA低甲基化水平与其高表达密切相关，提示表观遗传学机制在肝细胞癌发生发展中起重要作用。试剂盒检测范围为23.5 pg/mL-1500 pg/mL，可在科研场景中用于探索CENPK在细胞增殖、分化及癌症发生发展中的分子机制，尤其适用于染色体动力学研究、肿瘤模型构建以及药物干预对染色体稳定性影响的体外实验，适用于分子生物学、肿瘤学等领域的蛋白功能研究。本品仅用于科研，不用于临床诊断，产品具体参数及操作步骤详见产品说明书。
