Milk proteins identified in the samples from Buddhas of Bāmiyān by LC-MSMS.

Proteins were identified by searching UniprotSprot database with MSMS Ion search Mascot software (Matrix Science) with Chordata as the taxonomy restriction, with deamidation on Gln and Asn, oxidation on Met, pyro-Glu formation at Gln at the N-terminus of peptides as variable modifications. Only proteins identified with at least two peptides were considered as significant. Details of the identifications are reported in S5 File.
