一般描述

α-氰基-4-羟基肉桂酸(CHCA)经过特殊纯化,可作为肽MALDI-MS(基质辅助激光解吸电离-质谱)校准标准品的基质。CHCA增强了基质辅助激光解吸电离(MALDI)质谱仪中蛋白质或肽标准品和样品的电离。
它也可作为我们ProteoMass MALDI校准试剂盒(MS-CAL1和MS-CAL3)的一部分提供。

应用

α-氰基-4-羟基肉桂酸已被用作MALDI-TOF MS(基质辅助激光解吸电离-飞行时间质谱)分析的基质。该基质也已用于样品的制备。

包装

无底玻璃瓶。内含物装在插入的融合锥内。

实验方案

Mass Spectrometry of Glycans

The development of modern mass spectrometry (MS) equipment with high resolution and mass accuracy has led to its use in analyzing glycans for both profiling and structural studies.

聚糖的质谱

该聚糖质谱分析方案,被称之为干液滴法,基于原始的MALDI实验并依然是MS领域中最常用的方法。
