产品介绍
使用该 ALP 酶开发了一项试验,以评估两种蛋白 CRP-1 和 CRP-2 的冷冻保护活性。该酶已用于抑制前列腺酸性磷酸酶的环核苷酸类似物的抑制研究(使用荧光试验)。它在检测系统中常用作“报告者”,即与特异性识别靶分子的蛋白(抗体、链霉亲和素等)偶联。碱性磷酸酶也被用于去磷酸化酪蛋白。本产品在发酵或纯化过程中未使用任何动物源材料。碱性磷酸酶可与抗体及其他蛋白质偶联而用于ELISA、免疫印迹和组织化学检测。它通常用于使蛋白质和核酸去磷酸化。当需要高灵敏度时,可用于蛋白标记。碱性磷酸酶也可用于使DNA或RNA的5′-末端去磷酸化以防止自连。在用碱性磷酸酶去磷酸化后,DNA或RNA也可用放射性标记的磷酸盐(通过T4多核苷酸激酶)进行标记。产物 P8361 已被用于去磷酸化 Dishevelled (Dvl),这是 Wnt/β-连环蛋白信号通路中的关键组分 。 Alkaline phosphatase is used for conjugation to antibodies and other proteins for ELISA, Western blotting, and histochemical detection. It is routinely used to dephosphorylate proteins and nucleic acids. It may be used for protein labeling when high sensitivity is required. Alkaline phosphatase may be also be used to dephosphorylate the 5′-termini of DNA or RNA to prevent self-ligation. DNA or RNA can also be tagged with radiolabeled phosphate (via T4 polynucleotide kinase) after dephosphorylation with alkaline phosphatase. Product P8361 has been used to dephosphorylate Dishevelled (Dvl) , which is a key component in the Wnt/β-catenin signaling pathway . An assay, using this ALP enzyme, was developed to assess the cryoprotective activity of two proteins CRP-1 and CRP-2. The enzyme has been used for inhibitory studies of cyclic nucleotide analogs that inhibit prostatic acid phosphatase using a fluorogenic assay. It is commonly used as a 'reporter' in detection systems, in which it is conjugated to a protein (antibody, streptavidin, etc.) that specifically recognizes a target molecule. Alkaline phosphatase has also been used to dephosphorylate casein. The product is manufactured without the use of any animal source materials during fermentation or purification.
生化机理
碱性磷酸酶使蛋白质和核酸去磷酸化。碱性磷酸酶是由两个相等的亚单位组成的二聚体。 这种酶是一种糖蛋白,含约 12% 的碳水化合物(6% 己糖和 6% 其他中性糖)。每个碱性磷酸酶分子含有四个锌原子和四个二硫键。 在镁存在的情况下,碱性磷酸酶活性达到最大。 对磷酸对硝基苯基磷酸酯、磷酸苯酯、磷酸酚酞、α-甘油磷酸酯、β-甘油磷酸酯、2-磷酸甘油酯、磷酸丙糖酯、葡萄糖6-磷酸、葡萄糖 1-磷酸、果糖 1-磷酸、果糖 6-磷酸、腺苷 5-磷酸腺苷 3-磷酸、磷酸烯醇丙酮酸和 β-烟酰胺腺嘌呤二核苷酸磷酸等磷酸单酯的水解进行催化。 砷酸盐、半胱氨酸、碘、无机磷酸盐、焦磷酸盐、磷酸二异丙酯、三苯基磷酸盐、氟磷酸二异丙酯和 L-苯丙氨酸是碱性磷酸酶的一些强抑制剂。 该酶在 pH 7.5-9.5.2 范围内最稳定,酶活性的最适 pH 为 pH 8-10。
