2D gel is dying in US. Lots of ppl in China and Europe still use it. And PMF is dying as well. Get MS/MS if you can. 误差 is not major issue for PMF. PMF can't handle complex samples. With current MS technology, you can ID multiple proteins even from 2D gel spots.

PMF is pattern match (no sequencing information). If you have multiple proteins in that spot, most likely you can only detect the most abundant protein by PMF. MS/MS will give you sequence information and can detect multiple proteins. Even with 2D gel, which arguably is "high resolution" separation, it's quite frequent that you will get multiple proteins in 1 spot.
