A kind of protein complexes of cytochrome C with L-Arg was observed. Using L-Arg a strategy for probing the structural information of cytochrome C and protein complexes was established. At low pH solution multiply L-A...
Time-of-flight mass spectrometry (TOF-MS) is widely used in protein chemistry and proteomics research due to its high sensitivity , resolution and accuracy. Recently we have developed two Q-TOF-MS analytical systems t...
An auxiliary electrode was used to improve the electric field distribution between the nESI emitter and the MS sampler. The results show an improvement in the ratio of signal to noise for nanoliter electrospray using ...
