Mass spectra of proteins such as ribonucleaseA and lysozyme were obtained with substantially enhanced abundant peaks of low charge states.
采用核糖核酸A、溶菌酶等样品和商品化的线性离子阱质谱仪对该电离源进行了表征。

For example, by random folding, the amino-acid chain of the enzyme ribonuclease, a small protein, could adopt more than 1040 different shapes, which would take billions of years to explore.
