产品名称 S100P Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21; however, this gene is located at 4p16. This protein, in addition to binding Ca2+, also binds Zn2+ and Mg2+. This protein may play a role in the etiology of prostate cancer. [provided by RefSeq]

PubMedPubMed 靶点与功能 SAA(Serum Amyloid A)是多基因家族编码的急性时相反应蛋白,核心功能与研究价值包括: 炎症“快速响应者”:在感染、创伤或炎症刺激下,肝细胞在IL-1/IL-6/TNFα调控下4-6小时内表达升高1000倍,病原体清除后24-48小时迅速降至正常水平(半衰期约1天); 感染鉴别诊断:病毒感染时SAA显著升高(如流感病毒感染可达500mg/L),而CRP正常或轻度升高;细菌感染时二者均显著升高,联合检测可提高早期诊断特异性(AUC=0.92); 疾病关联:慢性升高与动脉粥样硬化(促进脂质沉积)、关节炎(滑膜炎症)、移植排斥反应相关,是肿瘤预后评估的潜在标志物(如肺癌患者SAA>10mg/L时5年生存率降低35%)。 实验操作关键要点 ELISA配对抗体检测(血清样本): 捕获抗体包被:重组单抗用碳酸盐缓冲液(pH9.6)稀释至1μg/mL,4℃包被过夜,PBST洗涤3次; 样本处理:血清1:1000稀释(避免hook效应),37℃孵育1小时; 信号检测:HRP标记检测抗体(1:5000稀释),TMB显色15分钟,450nm处OD值与SAA浓度呈良好线性(R²≥0.99,检测范围0.1-200mg/L)。 WB验证(炎症模型样本): 样本制备:LPS刺激RAW264.7细胞24小时,RIPA裂解液(含1mM PMSF)冰上裂解30分钟; 电泳条件:15% SDS-PAGE凝胶,恒压120V电泳90分钟,转膜至0.22μm PVDF膜; 结果判读:抗体1:500稀释,4℃孵育过夜,12kDa处可见特异性条带,刺激组灰度值为对照组的8-10倍。 IHC-P组织染色: 阳性定位:肝脏组织中肝细胞胞质呈棕黄色阳性(炎症模型中表达增强); 注意事项:避免使用淀粉样变性组织(SAA沉积可能导致非特异性结合)。 公司正在出售的产品
