Anaspec SensoLyte pNPP ALP Assay Kit 堿性磷酸酶活性檢測

簡要描述:

Anaspec SensoLyte pNPP ALP Assay Kit 堿性磷酸酶活性檢測:對硝基苯酚磷酸鹽(pNPP)是一種常用的堿性磷酸酶(ALP)顯色底物,堿性條件下能被ALP催化生成對硝基酚(para-nitrophenol,p-nitrophenol),呈黃色產(chǎn)物,可在400-415nm檢測到吸光度。產(chǎn)物黃色越深,代表ALP活性越高,反之則酶活性越低。則通過比色分析可定量檢測ALP水平

 產(chǎn)品關鍵詞:

Phosphatase, Alkaline堿性磷酸酶;ALP/AKP;對硝基苯酚磷酸鹽(pNPP);偶氮偶聯(lián)法;顯色法(定量);染色法(定性); 

 

基本介紹:

堿性磷酸酶(Phosphatase, Alkaline,ALP/AP/AKP/ALKP/ALPase,EC 3.1.3.1),是一種含兩個相同亞基的二聚體,也是一種約含12%碳水化合物(6%己糖和6%其他中性糖)的糖蛋白,每個ALP分子含4個鋅離子和4個二硫鍵。鎂離子存在情況下,ALP可達到zui高酶活。堿性條件下,ALP能催化磷酸單酯水解,比如對硝基苯酚磷酸鹽(pNPP)、磷酸苯酯、葡萄糖-6-磷酸、葡萄糖-1-磷酸、果糖-6-磷酸、腺苷-5-磷酸等。

? 常見的堿性磷酸酶ALP包括腸道堿性磷酸酶(如小牛腸來源,calf intestinal)、胎盤堿性磷酸酶(placental alkaline phosphatase)、非組織特異性堿性磷酸酶(tissue-nonspecific isozyme, alkaline phosphatase)等。

ALP常用來偶聯(lián)抗體和其他蛋白,從而滿足ELISA、WB和組織化學檢測上的應用。通常用來蛋白的去磷酸化實驗,比如酪蛋白和核酸等。當需要高檢測靈敏度時也能用來蛋白標記。還可用在DNA或RNA 的5′-末端去磷酸以防止自連。經(jīng)堿性磷酸酶的去磷酸化作用后,DNA 或 RNA 還可被放射性標記磷酸鹽標記(通過 T4 多核苷酸激酶)。

 

研究意義:
堿性磷酸酶(ALP)活性的變化與一系列生理和病理事件緊密關聯(lián),比如骨骼發(fā)育、骨骼相關疾病、ren娠相關疾病和炎癥性腸病(inflammatory bowel diseases)等。正因如此,ALP被用作衡量生理特征或疾病的參照指標。另外,ALP活性檢測在環(huán)境監(jiān)測、食品質量控制等方面也呈現(xiàn)重要作用。? 干細胞如誘導多潛能干細胞iPS,ALP活性很高,則ALP常被用作iPS誘導成功的標志;? 分化的結腸癌細胞內ALP活性顯著提高,則ALP常被當做結腸癌細胞分化程度的指標(定性/定量);? 血清中ALP水平提高,被稱作高堿性磷酸酶血癥,此癥狀被認為和惡性膽管阻塞、原發(fā)性膽管硬化、原發(fā)性硬化膽管炎、肝淋巴瘤和肝肉瘤等肝膽疾病密切相關;? ALP是成骨細胞的副產(chǎn)物,血清中ALP活性升高和骨頭發(fā)育密切關聯(lián);? 血清ALP活性過低也與一些疾病相關;? 兒童和孕婦血清內ALP活性較常人高一些;血清中ALP活性范圍在20-140U/L。

檢測原理(堿性磷酸酶活性):

對硝基苯酚磷酸鹽(pNPP)是一種常用的堿性磷酸酶(ALP)顯色底物,堿性條件下能被ALP催化生成對硝基酚(para-nitrophenol,p-nitrophenol),呈黃色產(chǎn)物,可在400-415nm檢測到吸光度。產(chǎn)物黃色越深,代表ALP活性越高,反之則酶活性越低。則通過比色分析可定量檢測ALP水平。反應式如下:



檢測對象:細胞或組織裂解液或勻漿液、血清、血漿、尿液等樣品內源性堿性磷酸酶活性。
