产品名称 Arginase 1 Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍Arginase I which is expressed almost exclusively in the liver, catalyzes the conversion of arginine to ornithine and urea . The human arginase I gene, which maps to chromosome 6q23, encodes a 322 amino acid protein. Arginase I exists as a homotrimeric protein and contains a binuclear manganese cluster. Arginase II catalyzes the same reaction as arginase I, but differs in its tissue specificity and subcellular location. Specifically, arginase II localizes to the mitochondria. Arginase II is expressed in non-hepatic tissues, with the highest levels of expression in the kidneys, but, unlike arginase I, is not expressed in liver. The human arginase II gene, which maps to chromosome 14q24.1-q24.3, encodes a 354 amino acid protein. In addition, arginase II contains a putative amino-terminal mitochondrial localization sequence.

PubMedPubMed 靶点与功能 ARG1(Arginase 1)作为尿素循环关键酶(分子量35kDa),核心研究价值体现在: 肝特异性标志物:肝细胞胞质高表达,催化L-精氨酸水解为鸟氨酸和尿素,是肝功能评估金标准(肝切除后ARG1表达量与剩余肝体积正相关,R²=0.82); 肿瘤免疫调节枢纽:肿瘤相关巨噬细胞(TAM)通过高表达ARG1消耗微环境中的L-精氨酸,抑制CD8⁺T细胞增殖(ARG1⁺TAM占比每增加10%,T细胞浸润减少23%); 代谢疾病机制:在非酒精性脂肪肝(NAFLD) 模型中,ARG1活性降低导致血氨升高和胰岛素抵抗,抗体检测可动态追踪疾病进展。 实验操作关键要点 IHC-P肝衰竭模型检测: 抗原修复:柠檬酸盐缓冲液(pH6.0)微波修复20分钟(石蜡切片),正常肝细胞胞质呈强阳性,肝衰竭时阳性区域缩小至汇管区周围(残存肝细胞); 阳性对照:正常大鼠肝脏组织(中央静脉周围肝细胞阳性率>90%); 肿瘤样本应用:肝癌间质中ARG1⁺TAM呈“圆形胞质阳性”,与CD206抗体共染可定义M2型巨噬细胞(ARG1⁺CD206⁺占比>40%提示免疫抑制微环境)。 WB代谢通路验证: 样本处理:db/db糖尿病小鼠肝组织,用含磷酸酶抑制剂(PhosSTOP) 的RIPA裂解液冰上裂解30分钟,14000g离心20分钟取上清; 抗体稀释:抗体1:2000稀释(5% BSA+TBST),4℃孵育过夜,HRP二抗1:5000室温孵育1小时,35kDa处显带; 结果对比:糖尿病组ARG1表达量为对照组的1.5-2倍(代偿性升高),伴下游鸟氨酸脱羧酶(ODC)活性增加。 IF细胞共定位: RAW264.7巨噬细胞经IL-4刺激(20ng/mL,48小时)诱导ARG1表达,与iNOS抗体共染(M1型标志物),ARG1(绿色)与iNOS(红色)在不同巨噬细胞亚群中呈“互斥表达”(M2型ARG1⁺iNOS⁻,M1型反之)。 公司正在出售的产品
