SP3 protocol optimised for foodcrust protein extraction from archaeological cooking vessels. protocols.io https://dx.doi.org/10.17504/protocols.io.e6nvwb22wvmk/v11754-218910.17504/protocols.io.e6nvwb22wvmk/v1http://hdl.handle.net/10034/629230A SP3-based protocol developed for the extraction of proteins from charred organic residues (foodcrust) found on cooking vessels. This protocol is to prepare samples for MALDI-ToF MS and LC-MS/MS analysis. We recommend starting with a batch size of 2-10 samples, and including flanking negative controls (blanks) to test for any downstream contamination.CC BY 4.0 Attribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/PalaeoproteomicsProteinsPotteryOther1750-2799protocols.io
