Alkaline phosphatase is highly purified from calf intestine. Alkaline phosphatase (ALP) removes phosphate groups from the 5' end of DNA and RNA, and from proteins, at high pH. Most mammals have 4 different isozymes: placental, placental like, intestinal and non tissue specific (found in liver, kidney and bone). Tissues with particularly high concentrations of ALP include the liver, bile ducts, placenta, and bone. Damaged or diseased tissue releases enzymes into the blood, so serum ALP measurements can be abnormal in many conditions, including bone disease and liver disease. Typical uses in the lab for alkaline phosphatases include removing phosphate monoesters to prevent self-ligation, which is undesirable during plasmid DNA cloning. Another important use of alkaline phosphatase is as a label for enzyme immunoassays. 堿性磷酸酶（ALP或AKP）是廣泛分布于人體肝臟、骨骼、腸、腎和胎盤(pán)等組織經(jīng)肝臟向膽外排出的一種酶。 在免疫學(xué)研究方面, 已廣泛應(yīng)用AP 標(biāo)記抗體進(jìn)行酶聯(lián)免疫熒光反應(yīng)(E LISA)和Western 印跡分析, 即將A P 與顯色劑或去磷酸化后能發(fā)光的底物相互作用來(lái)揭示靶與檢測(cè)酶復(fù)合物的存在, 與辣根過(guò)氧化物酶相比, AP 用作標(biāo)記酶的優(yōu)點(diǎn)是穩(wěn)定性高、靈敏度高, 缺點(diǎn)是成本高、標(biāo)記困難。在生物化學(xué)和分子生物學(xué)方面, 用AP 催化除去DNA 分子的5′末端磷酸基團(tuán)以防止載體自連是基因克隆中的常規(guī)手段之一。 |
