Crosslinking mass spectrometry requires a set of standards to enhance the communication within the field but also to facilitate the use of crosslink data by other fields. Specifically, wwPDB has requested the deposition of crosslink data in a field repository and in a field-agreed standard format such that modellers can draw on published crosslink data in their efforts. Please contribute to our Standards Initiative by contributing your thoughts through our on-line form (below). Feel free to forward the link to any interested crosslinking aficionado that may not have been able to attend 9th SSP.
