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。

We present a new MALD1 sample preparation technique for peptide analysis using the matrix alpha-cyano-4-hydroxy-cinnamic acid (CHCA) and prestructured sample supports. The preparation integrates sample purification, based on the affinity of microcrystalline CHCA for peptides, thereby simplifying the analysis of
a-Cyano-4-hydroxycinnamic acid as a matrix for matrixassisted laser desorption mass spectromtry.
