Crosslinks in Soluble Extract of DSSO Crosslinked Intact Tetrahymena thermophila Cilia


ABSTRACT: Intact cilia were isolated from dibucaine-treated Tetrahymena thermophila and subjected to DSSO crosslinking. Following quenching of the DSSO, a soluble "membrane and matrix" extract was generated by the addition of buffer containing 1% NP-40. The insoluble axonemes were removed by centrifugation and the supernatant extract was digested with trypsin, and crosslinked peptides were enriched using size exclusion chromatography. Crosslinks were identified using an MS2-MS3 data collection method and the Proteome Discoverer XlinkX node. Crosslink searching used a smaller fasta generated from analysis of the .RAW files and the Basic Sequest workflow.
