Thermo Scientific Melon 凝胶色谱纯化柱是一款便利、即用型的预填充色谱柱,它用于分离和纯化抗体。我们的 Melon 凝胶 IgG 纯化树脂是传统蛋白 A 和蛋白 G 方法的更简单、更快的替代方法,用于从血清和其他来源中纯化人、小鼠和兔 IgG。

Melon 凝胶 IgG 纯化树脂的特点:

简单、一步式方案—使用 Melon 凝胶树脂进行 IgG 纯化不需要蛋白 A 和蛋白 G 所需的结合、洗涤和多次洗脱步骤
快速纯化—从血清中纯化抗体的速度是蛋白 A 或 G 方法的四至六倍
高回收率和纯度—许多物种的血清抗体回收率大于 90%,纯度大于 80%
较小稀释度—降低在储存或使用前对抗体进行浓缩的需求
温和纯化—无需苛刻的抗体洗脱条件来帮助保留 IgG 活性
可再生支持物—Melon 凝胶树脂可用于多次抗体纯化

这些纯化柱兼容主流自动液相色谱系统或手动注射器处理并直接连接 ÄKTA™ 或 FPLC 系统(无需额外的连接器)。每件产品均随附一个附件包,已预装在纯化柱上,与 Luer-Lok 注射器接头或 1/16” 管配合使用。Melon 凝胶纯化柱实现快速、简单和可重复的色谱分离并且可以多次使用。

Melon 凝胶 IgG 纯化树脂能纯化血清和其他样品类型的抗体。Melon 凝胶树脂可结合和去除血清蛋白,因此可以在流过物组分中收集纯 IgG。该程序温和,因为不涉及苛刻的洗脱条件。

Melon 凝胶树脂包含具有专利技术的配体,其可保留在血清、腹水和培养物上清液中发现的大多数蛋白,同时使 IgG 通过支持物并收集在流过物组分中。由于 Melon 凝胶树脂不是结合和释放支持物,其非常快速且对抗体温和,得到具有高纯度和高活性的抗体制剂。

Melon 凝胶树脂可与多种物种和亚类的抗体(其中许多使用蛋白 A 或蛋白 G 时无法高效纯化)配合使用。通过该方法分离的 IgG 的所得回收率和纯度与使用结合和释放支持物(如蛋白 A 或蛋白 G)从相同样品中获得的回收率和纯度相当。此外,使用 Melon 凝胶树脂纯化的抗体可回收并立即用于免疫检测或后续偶联或修饰步骤;回收的抗体无需通过中和或脱盐来去除苛刻的洗脱缓冲液。

与传统蛋白 A 或蛋白 G 方法相比,Melon 凝胶 IgG 纯化可节约时间,且不影响抗体的质量。与采用蛋白 A 或蛋白 G 的抗体亲和纯化相比,Melon 凝胶 IgG 纯化更加简单、快速,产量和纯度也更高,适用于更广泛的抗体类型。

常见问题解答 (FAQ)

How can I determine when the Melon Gel Support is saturated?

For serum, a volume double the Melon Gel Support volume is the maximum amount that can be processed at one time. To determine if too much sample was processed, examine the purified IgG by SDS-PAGE for additional protein bands.

Can Melon Gel purify chicken IgY?

No. Thermo Scientific Thiophilic Adsorbent (Cat. Nos. 20500 and 44916) can be used to purify IgY from serum. The Chicken IgY Purification Kit (Cat. No. 44918) can be used to purify IgY from egg yolks.

Is the Melon Gel IgG Spin Purification Kit (Cat. No. 45206) a viable alternative to using traditional Protein A and Protein G methods for purification of IgG from serum?

Yes. With the Melon Gel IgG Spin Purification Kit, 90% recovery of IgG with greater than 80% purity are typically observed for a single purification. Although IgA and IgM may be present along with the purified IgG, a high percentage (> 80%) of IgA and IgM is retained on the gel support. This high binding of IgA and IgM to the gel support combined with the fact that IgA and IgM are present in low abundance in serum results in low levels of these antibody molecules in the purified IgG. Here are other advantages of using the Melon Gel IgG Spin Purification Kit over traditional Protein A or Protein G methods:
-Simple, one-step protocol - IgG purification with Melon Gel Resin does not involve binding, washing, and multiple elution steps required by Protein A and Protein G
-Rapid purification - antibody purification from serum is four to six times faster than Protein A or G methods
-Minimal dilution - reduced need to concentrate antibody before storage or use
-Robust purification - Melon Gel IgG Purification Kits work with a wide range of antibodies including many that do not purify well on Protein A or Protein G
-Gentle purification - No harsh antibody elution conditions helps retain IgG activity
-Regenerable support - Melon Gel Resin can be used for multiple antibody purifications

How many times can I reuse the Melon Gel Support?

The Melon Gel Support can be used up to three times. Performing an ammonium sulfate precipitation on serum samples containing large amounts of non-antibody protein before purification improves purification efficiency and increases reusability.

After Melon Gel purification, must I desalt or dialyze the purified antibody before using the Thermo Scientific Direct IP Kit (Cat. No. 26148)?

No. However, researchers may want to add an equal volume of binding buffer to elevate the pH towards neutral.
