SDS-lysed patient and cell line samples were processed and digested according to the filter-aided sample preparation (FASP) method [23 (link),24 (link)]. All of the filter-processed samples used 20 μg of protein material. Peptides from both patient and cell line samples were cleaned up with the Oasis HLB μElution (Waters, Milford, MA, USA) protocol.4.4. Liquid Chromatography (LC)-MS Analysis.
Dried peptides were dissolved in 20 μL of 2% acetonitrile (ACN) and 0.5% formic acid (FA). Differently preserved THP-1 and Molm-13 samples were analyzed on an Orbitrap Elite mass spectrometer equipped with a nanospray Flex ion source coupled to an Ultimate 3000 Rapid Separation LC system (both from Thermo Scientific, Waltham, MA, USA). Approximately 0.5 μg peptides were pre-concentrated and separated, as previously described [5 (link)]. Patient samples without or with PBS wash(es) were analyzed on a Q Exactive HF Orbitrap mass spectrometer equipped with an Easy-Spray (Thermo Scientific) coupled to an Ultimate 3000 Rapid Separation LC system. Approximately 0.6 μg peptides were pre-concentrated on a 2 cm × 75 µm ID Acclaim PepMap 100 trapping column and separated on a 50 cm × 75 µm ID Easy-Spray PepMap RSLC analytical column (both from Thermo Scientific). Bound peptides were eluted within a 195 min run using a binary gradient with buffer A (0.1% FA in water) and buffer B (0.1% FA in ACN).

Samples from slides containing whole lung tissue sections were scraped excluding major blood vessels and processed as previously described (Herrera et al, 2020 (link)). Peptides were evaluated by liquid chromatography coupled tandem mass spectrometry using an UltiMate 3000 Rapid Separation LC system (Dionex Corporation) coupled to a Q Exactive HF mass spectrometer (Thermo Fisher Scientific). Raw spectra were aligned using MAXQuant software v1.6.17.0 (Cox & Mann, 2008 (link)) with the variable modifications of proline and methionine oxidation in addition to “matched between runs” being enabled. Raw data were then imported into R for differential analysis with MSqRob (Goeminne et al, 2018 (link)) using the default pipeline. Heat maps were plotted using scaled log10-transformed LFQ counts.

The instrument consisted of a Dionex-Ultimate® 3000 Rapid Separation LC system, which was equipped with an auto sampler, a quaternary pump, a degasser, a column oven, and a DAD detector.[22 (link)23 (link)] The chromatographic analysis was carried out using a reverse phase Acclaim Polar Advantage II C18 column. The column temperature was maintained at 40°C. The mobile phase was consisted of 0.1% formic acid solution (A) and acetonitrile (B) with gradient elution system as shown in Table 1 at a flow rate of 1 ml/min while the separation time was 18 min and the injection volume was 5 μl. The spectral data from the DAD-3000RS DAD was set at 210, 254 and 320 nm. For quantitative analysis, the wavelength was set at 320 nm. The peak identification was based on the retention time and the DAD spectrum against the standard presented in the chromatogram. The data acquisition was performed by Chromeleon software version 6.8 (Dionex, Thermo Fisher Scientific Inc.).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
