Thermo Scientific™ Pierce™ 蛋白浓缩管 (PES) 为一次性超滤离心管,配有聚醚砜(polyethersulfone,以下简称 PES)膜,用于生物样品的浓缩、脱盐和缓冲液置换。本产品的截留分子量 (MWCO) 为 30K,可处理体积为 5-20 mL 的样品。

Pierce 蛋白浓缩仪 (PES) 的特点:

•快速蛋白浓缩—可在 5-30 分钟内将 10K MWCO 的样品浓缩 10 至 30 倍(不同 MWCO 的产品所用时间可能不同)
• 出色的蛋白回收—典型的蛋白回收率 >90%
• 多功能性—可进行生物样品的浓缩、渗滤或缓冲液置换
• 兼容性—可与固定角转头和吊篮式转头兼容;无需反转离心即可采集和回收样品

为易于识别,每个装置侧面蚀刻了 MWCO 值。为利于添加样品和回收,每个管侧面均有带刻度的透明窗口,以便目视测定截留体积。膜的垂直设计可实现高通量率、低非特异性结合和可忽略不计的膜上蛋白聚集;并提供了可靠且一致的结果。

Pierce 蛋白浓缩仪 (PES) 包含的膜可用于截留分子量比 PES 膜 MWCO 至少高出 2 倍的分子。使用小于推荐分子量的浓缩管,可能会降低回收率。蛋白回收率会因样品中的特定蛋白质及其起始浓度不同而变化。要实现蛋白回收率 >90%,蛋白样品浓度至少为0.1 mg/mL。

常见问题解答 (FAQ)

Can I reuse the Pierce Protein Concentrator PES, 30K MWCO, 2-6 mL (Cat. No. 88521)?

No, these concentrators are single-use, disposable ultrafiltration devices and are not intended for re-use.

Find additional tips, troubleshooting help, and resources within our Protein Purification and Isolation Support Center.

Can I autoclave PES protein concentrators?

We do not recommend autoclaving the PES protein concentrators. High temperatures will significantly increase the membrane molecular weight cutoff (MWCO). To sterilize, we recommend using a 70% ethanol solution.

Can I use PES protein concentrators for desalting and buffer exchange?

Yes, the PES membrane is compatible with desalting and buffer exchange. Protocols for concentrating, desalting, and buffer exchange only are provided in the product manuals.

How do PES protein concentrators work?

The protein concentrator columns have an upper compartment that holds the sample, and a lower compartment. The two compartments are separated by a polyethersulfone (PES) semipermeable membrane. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber. The protein concentrator cassettes also contain a PES membrane and a unique channel design that ensures high optimal flux with no optimization effort. Unlike other systems, the fluid is passed parallel to the filter, rather than being pushed through a membrane perpendicularly, which can clog the filter. For maximum protein recovery in both columns and cassettes, samples should have a molecular weight two-fold greater than the molecular weight cutoff (MWCO) of the concentrator membrane.

What are the different sizes of PES protein concentrators you offer?

Pierce polyethersulfone (PES) protein concentrators are offered in six distinct MWCOs of 3K, 5k, 10K, 30K, 50K, and 100K, and the cassettes are offered in five membrane MWCOs of 3K, 10K, 30K, 50K, and 100K. The columns can process four different sample volumes ranges of 100-500 µL, 2-6 mL, 5-20 mL, and 20-100 mL, while the cassettes can process 0.5-6 L.
