PubMedPubMed 产品介绍Glucagon plays a key role in glucose metabolism and homeostasis. Regulates blood glucose by increasing gluconeogenesis and decreasing glycolysis. A counterregulatory hormone of insulin, raises plasma glucose levels in response to insulin-induced hypoglycemia. GLP-1 is a potent stimulator of glucose-dependent insulin release. Play important roles on gastric motility and the suppression of plasma glucagon levels. May be involved in thesuppression of satiety and stimulation of glucose disposal in peripheral tissues, independent of the actions of insulin. Have growth-promoting activities on intestinal epithelium. May also regulate the hypothalamic pituitary axis (HPA) via effects on LH, TSH, CRH, oxytocin, and vasopressin. Belongs to the glucagon family. 靶点与功能
胰高血糖素样肽-1(GLP-1)是肠促胰岛素激素,主要由回肠L细胞分泌,活性形式为GLP-1(7-36)酰胺(主要循环形式)和GLP-1(7-37)。其核心功能包括: 生理作用:葡萄糖依赖性促胰岛素分泌、抑制胰高血糖素释放、延缓胃排空、增强中枢饱腹感; 临床价值:GLP-1受体激动剂(如司美格鲁肽)已成为糖尿病和肥胖治疗的一线药物,抗体可用于检测内源性GLP-1水平或药物代谢动力学研究; 研究意义:通过ELISA或IHC定位L细胞分布,揭示GLP-1在代谢综合征中的作用机制。 实验操作关键要点
ELISA定量检测(血浆样本): 样本处理:采集EDTA抗凝血浆,立即加入DPP-4抑制剂(如西格列汀)防止GLP-1降解,-80℃保存; 包被条件:兔单抗用0.05M碳酸盐缓冲液(pH9.6)稀释至2μg/mL,4℃包被过夜; 检测要点:标准品需包含GLP-1(7-36)酰胺和GLP-1(7-37)两种活性形式,HRP标记二抗1:5000稀释,TMB显色15分钟。 IHC-P组织染色(肠道样本): 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L细胞胞质信号; 阳性定位:回肠黏膜L细胞胞质呈棕黄色颗粒状阳性,可与proglucagon抗体共染验证共表达; 对照设置:必须包含空肠组织(弱阳性)和GLP-1敲除小鼠肠道(阴性对照)。 公司正在出售的产品
