a method for rapid determination of molecular weight of lysozyme from chiken egg white by matrix-assisted laser desorption ionization mass spectrometry was represented in this paper.
本文介绍了一种用基本辅助激光解吸电离质谱法快速测定蛋清中溶菌酶相对分子质量的方法。
the experimental results show that excessively strong laser intensity will affect the desorption ionization and stability of ap and will cause part of ap to decompose into 3~8 new peptide structures.
实验结果表明了过强的激光强度会影响ap的稳定性,并引起部分ap分解成3~8种新的多肽结构。
matrix assisted laser desorption ionization (maldi) technology is one of the best mass spectrometry ionization technologies for macro molecules which was developed almost two decades ago.
