ZipTip吸管尖是一种末端带有约0.6微升层析介质的10微升吸管尖,不会出现死体积。它是质谱分析,HPLC,毛细管电泳和其他分析技术之前快速(数秒)浓缩、脱盐和分馏多肽、蛋白质或寡核苷酸的理想工具。
微量样品制备使用的吸管尖ZipTip
带有C18、C4或金属螯合树脂的新型10微升级的ZipTip吸管尖,是为质谱分析前浓缩和纯化1至100微升生物样品而开发的。
ZipTip是一种末端带有约0.6μL层析介质的10μL吸管尖,因此不会出现死体积。它是质谱分析、HPLC、毛细管电泳和其它分析技术之前快速(数秒种)浓缩、脱盐和分馏多肽、蛋白质或寡核苷酸的理想工具。
这种装置结构简单,使用方便。使用时,将其置于一个单管或多管的移液器、标准的22格钝端的HPLC针、或自动的液体操作/样品制备的工作站上。为了吸附样品,通过介质反复抽、吸几次。此时,污染物也以同样的方式被清洗掉。然后将浓缩、纯化后的样品用1-4μL相容的溶剂精确地洗脱,直接转移到质谱仪或小瓶中。对于那些要求较小洗脱量的应用(例如小于1μL),可用仅含0.2μL介质的微量规格。
ZipTip吸管尖以可重复和高回收的方式浓缩、纯化飞(母托)摩尔级至皮(可)摩尔级的多肽、蛋白质或寡核苷酸,改善了数据的质量。为了简化分析,还可以采用分步洗脱对复杂的多肽混合物进行分馏。由于ZipTip吸管尖是样品制备的快速实用装置,大大节约操作时间,几乎可以省掉层析技术中zui费精力的分离纯化难题。

Details

Supported sulfonic acids such as SiliaBond® Propylsulfonic Acid (SiliaBond SCX-2) are in a class of strong acids widely used in different fields of synthetic organic chemistry. Their applications are well known and are used in a large number of settings going from drug discovery laboratories up to manufacturing processes. Among these applications, we denote their uses as acid catalysts, stationary phases for ion chromatography and basic impurity scavengers. Meanwhile, the most common use is probably as a strong cation exchanger (SCX) for the amine “Catch and Release” purification technique in SPE cartridges.

SiliCycle offers SiliaBond Propylsulfonic Acid (SCX-2) and SiliaBond Tosic Acid (SCX). Both are considered strong cation exchanger as they maintain a negative charge throughout the pH scale. The aromatic ring of the SiliaBond Tosic Acid makes it slightly more acidic than the other. However, tests have demonstrated that they both have comparable strength. The difference between the two products is mainly in the selectivity. SiliaBond SCX-2 presents a slightly more non-polar character than the SiliaBond SCX, thus reducing secondary non-polar interactions with compounds.

Details

SiliaBond® Tosic Acid (SiliaBond SCX, Si-TsOH) is a versatile bound strong acid with a pka <<1. It is widely used for the scavenging of amines and other basic functionalities, including weakly basic anilines, borohydrides, and metals such as Ni and Ag. It can also be used as an acid catalyst for organic reactions. Si-TsOH can serve as an alternative method to quench reactions instead of aqueous or organic soluble acids.

Metals Removed

  • Best scavenger for: Rh & Sn
  • Good scavenger for: Ag, Cu, Ni, Pd, Pt, Ru & Zn

SiliaBond Tosic Acid has been optimized for use in organic applications. It will not dissolve in methanol or any other solvents. It delivers much higher recovery and has better flow characteristics than corresponding polymer.

The main application of SiliaBond Tosic Acid is as a strong cation exchanger (SCX) in “Catch and Release” purification of amines. It is also widely used as stationary phase in ion exchange chromatography (IEC). Please see SiliaBond Propylsulfonic Acid (SCX-2) for more information.
