•在一小时内检测到低至 0.002 U/mL 的 AChE 活性水平
•使用过量 AChE 检测到低至 0.3 µM 的乙酰胆碱水平
•实现 0.3 µM 至100 µM 乙酰胆碱的检测范围
•产品规格允许在多个时间点测量
•设计用于尽可能减少自发荧光干扰

AChE 活性可以使用 10-乙酰基-3,7-二羟基吩嗪(Amplex™ Red 试剂)进行间接监测,这是一种针对过氧化氢的灵敏荧光探针。AChE 将乙酰胆碱底物转化为胆碱,后者然后被胆碱氧化酶氧化为甜菜碱和过氧化氢。在存在辣根过氧化物酶的情况下,过氧化氢与 Amplex™ Red 试剂以 1:1 的化学计量比发生反应,生成具有强烈荧光的产物试卤灵。

因为试卤灵的最大吸收和荧光发射波长分别约为 571 nm 和 585 nm,所以大多数生物样品的自发荧光对其几乎没有干扰。采用纯化自电鳗的 AChE 的实验表明,Amplex™ Red 乙酰胆碱/乙酰胆碱酯酶检测试剂盒可以检测低至 0.002 U/mL 的 AChE,反应时间为 1 小时。通过在检测中提供过量的 AChE,该试剂盒还可用于检测低至 0.3 µM 的乙酰胆碱水平,检测范围为 0.3 µM 到 100 µM 乙酰胆碱。

Amplex™ Red 测定试剂盒可用于广泛的研究范围
可提供一系列经过验证的 Amplex™ Red 测定试剂盒进行细胞信号转导和脂质、神经生物学、炎症和免疫功能以及代谢方面的研究。我们还提供具有更高灵敏度和更明亮荧光的第二代试剂——Amplex™ UltraRed 试剂(货号 A36006)—具有更高灵敏度和更明亮荧光的第二代试剂以及 Amplex™ Red/UltraRed 终止试剂(货号:A33855)。Amplex™ Red/UltraRed 终止试剂允许使用者在确定的时间点轻松控制和终止荧光信号生成反应。加入终止试剂之后,荧光信号能够保持稳定状态至少 3 个小时。还提供定制检测设计和包装。

常见问题解答 (FAQ)

I'm using an Amplex Red kit, the reagent changes color to pink almost immediately in my own Krebs-Ringer buffer but not in HBSS. Why is this?

The components of Krebs-Ringer buffer (salts) should not cause oxidation of the Amplex reagent (which, in the presence of peroxidase and H2O2 oxidizes to resorufin, which is pink in color and fluorescent). Try water alone (the water used to make the Krebs-Ringer buffer). Since Hank's Buffered Saline Solution is typically purchased rather than made in the lab, it likely would not have the same contaminant. Another option is to degas the buffer prior to use to removed dissolved oxygen radicals.

Can Amplex Red Assays be performed using cell lysates?

This is not recommended. The presence of endogenous proteases can complicate the assay by degrading the horseradish peroxidase (HRP). Endogenous peroxidases and antioxidants can modify the H2O2 required for the reaction, competing with HRP (and catalase) for the substrate.

The Amplex Red Assays are best performed with either purified enzymes or extracted H2O2 in a defined buffer system, extracellular solutions or body fluids (media, serum, etc.) that do not exhibit high levels of endogenous protease or oxidase activity and do not contain antioxidants.

'Most of the current clinical treatments for Alzheimer''s disease (AD) are largely symptomatic and can have serious side effects. We have tested the feasibility of using the granulocyte colony-stimulating factor (G-CSF), which is known to mobilize hematopoietic stem cells (HSCs) from the bone marrow into the peripheral blood, as a ... More

'Mesenchymal stem cells (MSCs) are located primarily in the bone marrow and are characterized by their capacity to differentiate into mesenchymal lineages such as bone, fat, and cartilage in response to appropriate signals.

'Bladders from patients with detrusor overactivity have an increased atropine-resistant contractile response to nerve stimulation.
