pLink 2

pLink® is a software dedicated for the analysis of chemically cross-linked proteins or protein complexes using mass spectrometry.

pLink 2 is developed as an upgrade of pLink 1. Compared with pLink 1, pLink 2 provides a graphical user interface, and is ~40 times faster with a newly designed index structure. There are also some improvements in the precision.

Our paper A high-speed search engine pLink 2 with systematic evaluation for proteome-scale identification of cross-linked peptides has been accepted for publication by Nature Communications. Congratulations and please cite this paper if you used pLink 2.
