Alexa Fluor™ 610-X 是一种明亮且光稳定的 Texas Red™ 染料替代品。Alexa Fluor™ 610-X 染料用于成像和流式细胞分析中稳定信号的生成,具有水溶性和 pH 值不敏感性(pH 值 4 至 pH 值 10)。除反应性染料制剂外,我们还提供用于流式细胞分析的 Alexa Fluor™ 610–R-藻红蛋白串联抗体偶联物。Alexa Fluor™ 610-X 的 NHS 酯(或琥珀酰亚胺酯)是将该染料偶联至蛋白或抗体的常用工具。NHS 酯可用于标记蛋白、胺修饰的寡核苷酸和其他含胺分子的伯胺 (R-NH2)。所得 Alexa Fluor™ 偶联物将显示出比其他光谱相似荧光基团的偶联物更亮的荧光和更高的光稳定性。

关于该 AlexaFluor™ NHS 酯的详细信息:

荧光基团标记:Alexa Fluor™ 610-X 染料
反应性基团:NHS 酯
反应性:蛋白和配体、胺修饰的寡核苷酸上的伯胺
偶联物的 Ex/Em:603/623 nm
消光系数:144,000 cm-1M-1
光谱类似染料:Texas Red™
分子量:1284.8

典型偶联反应
您可以将胺反应性试剂与几乎任何蛋白或肽偶联(提供的方案针对 IgG 抗体进行了优化)。您可以针对任何量的蛋白按比例缩放反应,但为了获得最佳结果,蛋白的浓度应至少为 2 mg/mL。我们建议使用三种不同的反应性试剂/蛋白摩尔比进行三种不同程度的标记。

Alexa Fluor™ NHS 酯通常溶于高质量的无水二甲基甲酰胺 (DMF) 或二甲亚砜 (DMSO) (D12345) 中,并在 0.1–0.2 M 碳酸氢钠缓冲液(pH 值 8.3)中于室温下进行反应,持续 1 小时。由于末端胺的 pKa 低于赖氨酸 ε-氨基基团的 pKa,您可以使用接近中性 pH 值的缓冲液对胺末端进行更具选择性的标记。

偶联物纯化
通常使用凝胶过滤柱(如 Sephadex™ G-25、BioGel™ P-30 或等效柱)将标记抗体与游离 Alexa Fluor™ 染料分离。对于更大或更小的蛋白,选择具有适当分子量滤除点的凝胶过滤介质或通过透析纯化。我们提供了多种优化的纯化试剂盒,可用于不同量抗体偶联物:
0.5-1 mg 用抗体偶联物纯化试剂盒 (A33086)
20-50 µg 用抗体偶联物纯化试剂盒 (A33087)
50-100 µg 用抗体偶联物纯化试剂盒 (A33088)

常见问题解答 (FAQ)

I am labeling a protein with Alexa Fluor 488 SDP ester. The manual recommends using a sodium bicarbonate buffer at pH 8.3. Can I use a different buffer instead?

Yes. The important thing is to use a buffered solution with a pH between 8.0 and 8.5. Do not use Tris buffer, which has amine groups. Most other buffers will work fine in that pH range. This is also true for other amine-reactive dyes, such as succinimidyl (NHS) esters or TFP esters.

I am not going to use all of my Alexa Fluor succinimidyl ester reactive dye. Can I just make it up in DMSO and store aliquots at -20 degrees C?

This is not recommended. Any trace amounts of water in the DMSO can promote spontaneous hydrolysis over time. Even if using anhydrous DMSO, DMSO is hygroscopic; it readily absorbs moisture from the atmosphere over time. A better alternative is to dissolve the reactive dye in a volatile solvent, make smaller aliquots and then evaporate off the solvent using a vacuum pump. The smaller aliquots of solid reactive dye should then be stored frozen, desiccated and protected from light. Contact Technical Support by sending an email to techsupport@thermofisher.com for the recommended volatile solvent.

Abstract
Oral instillation with surfactant phospholipid: a reliable alternative to intratracheal injection in mouse studies.
Authors:Yu H, Buff SM, Baatz JE, Virella-Lowell I,
Journal:Lab Anim
PubMed ID:18625584
'The intratracheal (IT) injection technique has been widely used in the mouse studies of pulmonary diseases. Here, we describe a non-invasive technique using oral instillation challenge with the surfactant phospholipid that may advantageously replace the traditional IT technique. We performed comparative studies between oral instillation and IT injection of both ... More
Biochemical and proteomic analysis of 'Dixiland' peach fruit (Prunus persica) upon heat treatment.

'Shipping of peaches to distant markets and storage require low temperature; however, cold storage affects fruit quality causing physiological disorders collectively termed ''chilling injury'' (CI). In order to ameliorate CI, different strategies have been applied before cold storage; among them heat treatment (HT) has been widely used. In this work, ... More

'The RIBOSOMAL PROTEIN L10 (RPL10) is an integral component of the eukaryotic ribosome large subunit. Besides being a constituent of ribosomes and participating in protein translation, additional extraribosomal functions in the nucleus have been described for RPL10 in different organisms. Previously, we demonstrated that Arabidopsis (Arabidopsis thaliana) RPL10 genes are ... More

'Peach (Prunus persica L. Batsch) is a climacteric fruit that ripens after harvest, prior to human consumption. Organic acids and soluble sugars contribute to the overall organoleptic quality of fresh peach; thus, the integrated study of the metabolic pathways controlling the levels of these compounds is of great relevance. Therefore, ... More
Plant L10 ribosomal proteins have different roles during development and translation under ultraviolet-B stress.

Journal:Plant Physiol
PubMed ID:20516338
Ribosomal protein L10 (RPL10) proteins are ubiquitous in the plant kingdom. Arabidopsis (Arabidopsis thaliana) has three RPL10 genes encoding RPL10A to RPL10C proteins, while two genes are present in the maize (Zea mays) genome (rpl10-1 and rpl10-2). Maize and Arabidopsis RPL10s are tissue-specific and developmentally regulated, showing high levels of ... More
