商品属性
产品介绍STATs (signal transducers and activators of transcription) were originally discovered as two proteins (STAT1 and STAT2) which were involved in interferon alpha (IFN alpha) and IFN gamma signal transduction. Since then, several additional STAT proteins have been identified (STAT3, 4, 5a, 5b, and 6). STATs undergo tyrosine phosphorylation in response to growth factor or cytokine signaling. This phosphorylation results in dimerization and translocation of STAT proteins to the nucleus. In some cases this process is mediated by JAK Kinases (Janus Kinases 1, 2, and 3). For maximum activation of these proteins, phosphorylation at specific tyrosine and serine residues may be required in STAT1 alpha, 3, 4, and 5. Specific functions of the various members of the STAT family are poorly understood. STAT3 has been shown to be activated by IFN alpha but not IFN beta. The transcription factors associated with STAT3 are cJun and cyclic AMP responsive enhancer binding protein (CREB). Deletion of the STAT3 gene in knock out mice was lethal at the early embryonic stage.

靶点与功能
碱性磷酸酶(Alkaline Phosphatase, ALP)是一类非特异性磷酸单酯酶,在碱性条件下(最适pH 9.5-10.5)催化磷酸酯水解,主要功能包括:
组织特异性亚型:
肝型(L-ALP):肝胆疾病(如胆汁淤积)时血清水平显著升高;
骨型(B-ALP):骨代谢活跃(如佝偻病、骨肉瘤)时释放入血;
肠型(I-ALP)、胎盘型(P-ALP) 及肾型(R-ALP),各亚型具有独特的临床诊断意义;
临床价值:血清ALP活性是肝胆疾病、骨病的重要指标(正常参考值:成人40-150 U/L,儿童/青少年因骨骼生长可高达成人3倍);
研究意义:用于ALP同工酶分离、酶活性调控机制及酶替代疗法(如低磷酸酯酶症)研究。
实验操作关键要点
ELISA检测ALP同工酶:
亚型区分:使用肝/骨型特异抗体包被,可排除肠型ALP干扰(如餐后血清样本);
样本处理:血清需1:100稀释(含0.1% BSA的PBS),37℃孵育1.5小时,避免溶血样本(红细胞ALP干扰);
显色控制:ALP底物(如pNPP)在碱性条件下显色(405nm读取),反应时间严格控制30分钟(酶活性易受温度影响)。
IHC-P组织定位:
抗原修复:柠檬酸盐缓冲液(pH6.0)微波修复15分钟,增强肝/骨组织中ALP信号;
阳性定位:肝组织胆小管上皮细胞胞膜阳性,骨组织成骨细胞胞质/胞膜阳性;
对照设置:需包含胎盘组织(胎盘型ALP阳性对照)和ALP敲除细胞系(阴性对照)。
WB验证(组织裂解液):
样本制备:肝组织用含蛋白酶抑制剂(1mM PMSF) 的RIPA裂解液冰上裂解30分钟,12000g离心取上清;
电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,转膜采用0.45μm PVDF膜;
抗体孵育:抗体1:500稀释(5%脱脂奶粉+TBST),4℃孵育过夜,曝光时间45秒(二聚体条带80kDa为主)。
