去污剂在蛋白提取和样本制备过程中是很重要的物质，特别是研究疏水蛋白时。蛋白样本中

高浓度去污剂的存在能够影响ELISA,IEF 和蛋白的蛋白酶消化，以及用质谱进行分析时抑制

肽的离子化。

DetergentOUT™ GB-S10 树脂能够从蛋白水溶液和肽样本中去除自由的，未结合的阴离子的，

非离子或两性离子的去污剂(e.g. SDS, Triton® X-100 或CHAPS)，同时对于下游进行的质谱或

其他技术的分析应用带来的样本丢失。

DetergentOUT™ GB-S10 柱子在第三方的研究使用中表明完全兼容DI-QTOF 和 LC-MS/MS（请

见参考文献）。DetergentOUT™ GB-S10 柱子的使用显著增加到了检测到的肽光谱的数量。除

此之外，DetergentOUT™ GB-S10 柱子对于去污剂有高度的结合容量，比如每毫升固定的树

脂可以结合6mg SDS 和14mg Triton® X-100。

Figure 1: DetergentOUT™ GBS10 removes detergent & allows detection of peptide fragments by mass spectrometry. 500μg

phosphorylase B was digested in solution & then the indicated amount of detergent was added. Samples were treated with

DetergentOUT™ GBS10. Number of peptide spectra were determined as per the protocol of Alvarez, S. et al.

A. No detergent, No DetergentOUT™ GBS10 B. 0.5% CHAPS, DetergentOUT™ GBS10 treated

C. 0.5% CHAPS, No DetergentOUT™ GBS10

Figure 2: DetergentOUT™ GBS10 enhances mass spectrometry spectra. 5μg/μl protein mixture (BSA, cyctochrome C

and phosphorylase B) in water (Panel A) was supplemented with 0.5% CHAPS (Panel B and C). The CHAPS containing sample was

treated with DetergentOUT™ GBS10 and compared to an untreated sample (Panel C). Spectra were generated per Alvarez et al.

Figure 3: DetergentOUT™ GBS10 retains ≤6mg SDS per ml settled resin. SDS solution was continuously applied to

DetergentOUT™ GBS10 column. The graph depicts the amount of SDS detected in the flow- through. SDS was not

detected until fraction 7, so after 12mg SDS had been retained by the 2ml of DetergentOUT™ GB-S10 resin, resulting in a 6mg/ml

settled resin binding capacity.
