求翻译：Dr.Arbersold发明一种能呈现两种不同分子质量的试剂，这种试剂有三个组分：一个巯基团，可与还原的半胱氨酸残基反应；一个连接基团，可连接8个氢或8个重氢而产生轻重不同的两种化合物；以及一个生物素标记，可用于分离作标记的肽段。这种方法称为同位素标记法，或者是ICAT技术。是什么意思？

a dr.arbersold invention showing two different molecular weight reagents, this reagent has three components: a thiol group, the reaction with the cysteine ​​residues restored; a linking group can be connected to the eight hydrogen or eight deuterium arising from different levels of two compounds; an

Invention Arbersold Dr . A way to show two different elements of the quality of reagents reagents, and the three groups: one such mission, and the return of the cysteine residues response; a base, you can connect 8 or 8 hydrogen-deuterium and the two different compounds; as well as a biological mark

Dr.Arbersold invents one kind to be able to present two kind of different molecular masses the reagent, this reagent has three components: qiu groups and bases, but and return to original state cysteine remnant base response; Connection groups and bases, may connect 8 hydrogens or 8 heavy hydrogens

Dr.Arbersold invented a way to render two different molecular weights of reagents, this reagent has three components: a isooctyl mercaptoacetate group, reacts with cysteine residues restoring; a connection group can connect 8 8 heavy hydrogen or hydrogen and produce two different compounds and a bio
