推荐产品
應用
推荐用于抗体和蛋白质缀合的高比活性等级。
碱性磷酸酶可用于酪蛋白和其他蛋白质的去磷酸化。碱性磷酸酶还可用于 DNA 或 RNA 的 5′-末端的去磷酸化,以防止自我连接。经碱性磷酸酶的去磷酸化作用后,DNA 或 RNA 还可被放射性标记磷酸盐标记(通过 T4 多核苷酸激酶)。
生化/生理作用
该酶对醇类、胺类、焦磷酸盐以及酚类的磷酸酯具有广泛的特异性。常用于蛋白质和核酸的去磷酸化。
物理性質
牛肠碱性磷酸酶为二聚膜衍生糖蛋白。至少存在三种同工酶,每个单体通常拥有两个 N-连接多糖和一个或多个 O-连接多糖。2 该酶需要锌以及镁或钙二价离子才能显示活性。
牛肠道碱性磷酸酶是一种二聚化的膜衍生糖蛋白。其存在至少三种异构体,每个单体通常具有两个N-连接的和一个或多个O-连接的聚糖。

Intestinal alkaline phosphatase (IAP) regulates bicarbonate secretion, detoxifies lipopolysaccharide (LPS), regulates gut microbes, and dephosphorylates proinflammatory nucleotides. IAP also exhibits anti-inflammatory effects in a Toll-like Receptor-4 (TLR-4) dependent manner. However, it is not known whether IAP induces autophagy. We tested

In Alzheimer's disease (AD), abnormal sphingolipid metabolism has been reported, although the pathogenic consequences of these changes have not been fully characterized. We show that acid sphingomyelinase (ASM) is increased in fibroblasts, brain, and/or plasma from patients with AD and

Mechanosensitive osteocytes regulate bone mass in adults. Interleukin 6 (IL-6), such as present during orthodontic tooth movement, also strongly affects bone mass, but little is known about the effect of IL-6 on osteocyte function. Therefore we aimed to determine in

Phosphatases are involved in bone and tooth mineralization, but their mechanisms of action are not completely understood. Tissue-nonspecific alkaline phosphatase (TNAP, ALPL) regulates inhibitory extracellular pyrophosphate through its pyrophosphatase activity to control mineral propagation in the matrix; mice without TNAP
Nutrition reviews, 72(2), 82-94 (2014-02-11)
Important protective roles of intestinal alkaline phosphatase (IAP)--including regulation of intestinal surface pH, absorption of lipids, detoxification of free nucleotides and bacterial lipopolysaccharide, attenuation of intestinal inflammation, and possible modulation of the gut microbiota--have been reviewed recently. IAP is modulated
