Proteome of Deciliated Tetrahymena thermophila "Bodies" Fractionated by IEX or SEC.

ABSTRACT: Tetrahymena thermophil SB715 were deciliated by pH shock, collected by centrifugation, washed once and flash frozen. Lysate was made by grinding in liquid nitrogen and resuspension in buffer containing 0.2% NP40 with pipetting. Lysate was clarified by sequential centrifugations including 1 hour 130,000 x g 4C. Clarified lysate was fractionated by HPLC SEC or diluted to reduce salts to 22mM NaCl prior to fractionation by mixed-bed IEX. Fractions were reduced/alkylated and digested with trypsin for DDA LC-MS/MS. Data from SEC fractions was collected on an Orbitrap Fusion Lumos using a 75 minute top speed HCD method. Data from IEX fractions was collected on an Orbitrap Fusion using a 75 minute Topspeed CID method.

Proteomics of SEC and IEX fractionated Mouse Embryonic Stem Cells

Project description:Mouse embryonic stem cells were lysed in Pierce IP Lysis buffer and 2 mg of the clarified extract was fractionated on an HPLC SEC column and 2 mg was fractionated on an HPLC IEX mixed bed column. All fractions were reduced, alkylated, and trypsin digested for mass spectrometry as in Mallam et al. 2019 (PMID: 31665645). Data were collected on an Orbitrap Fusion mass spectrometer using a data dependent 75 minute topspeed method. Dissociation for SEC fractions was by CID, and for IEX fractions was by HCD. RAW files were converted to mzXML and searched using an MSBlender analysis pipeline.

Phaeodactylum tricornutum proteome from SEC and IEX fractionation of native extract

Project description:Phaeodactylum tricornutum (UTEX 646) grown without silica were used to generate a native protein extract. Extraction involved multiple freeze/thaw cycles, sonication, and solubilization in buffer containing 1% NP40. Following chromatographic separation by SEC or IEX the fractions were reduced/alkylated and digested with trypsin for LC-MS/MS on an orbitrap fusion. Data were collected using a 75 minute top speed DDA method with CID.

Protein Identification in Tetrahymena thermophila cilia IEX fractions used for XL-MS

Project description:Tetrahymena thermophila SB715 were deciliated by pH shock substituting HEPES for Tris in all subsequent buffers. Ciliry proteins were solubilized with buffer containing 1%NP40, and fractionated by HPLC on a mixed-bed IEX column. DSSO was added to 0.5 mM to all collected fractions. Crosslinking was quenched with Tris pH 8.0 at 28 mM and fractions were reduced, alkylated, and digested with trypsin for mass spectrometry. Spectra were collected on an Orbitrap Fusion Lumos using a DDA MS2-MS3 method for both protein and crosslink identification. Data in this deposition include the RAW files and MSBlender pipeline files used for protein identification. Crosslink analysis will be deposited separately.

Proteomic analysis of the soluble proteome of Thermochaetoides thermophila

Project description:The soluble proteome of Thermochaetoides thermophila (T. thermophilia) was analyzed to identify possible interaction of coeluting complexes for downstream integrative analysis using Co-fractionation/mass spectrometry (CF/MS). Mycelium of T. thermophilia was lysed and separated via size exclusion chromatography (SEC) and the Fractions were probed for their protein composition using LC-MSMS. Label-free Quantification was utilized to determine intra- and inter-fraction protein abundance, deriving information regarding, stochiometry and metabolic complex organization.
