产品描述：牛α2-HS糖蛋白(AHSG)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、组织匀浆样本中的AHSG含量。AHSG（α2-HS糖蛋白）是一种由肝脏分泌的血浆糖蛋白，与多种疾病如糖尿病、心血管疾病和结石等密切相关。其具有高度的遗传多态性，其基因多态性与糖尿病、血管钙化等疾病的易感性有关。AHSG在细胞过程中发挥多种作用，如促进内吞作用、调节骨的矿物质相、影响骨稳态等。试剂盒检测范围为125 ng/mL-8000 ng/mL，本产品可为畜牧业中牛群健康研究、营养代谢调控实验提供数据支持，例如骨骼发育研究、炎症相关疾病模型构建或免疫系统功能探索等科研方向，使用者可通过检测血清/血浆样本评估生理状态，或分析肝、肾等组织匀浆中的AHSG表达水平。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。
