WebbOne must remember, however, that when reduction and alkylation are performed, the alkylation results in carbamidomethyl-modified cysteine residues, which increase the mass of cysteine residues by 57.021 atomic mass units (amu), and this modification must be taken into account when performing the MS data searches.
Webb16 feb. 2024 · The reliability of mBBr labeling and IAM alkylation was validated by manually inspecting the MS2 spectra with representative spectra shown in Fig. 4A,B, and Fig. S4. Furthermore, cysteine modifications that were previously ignored or regarded as unstable for MS analysis were successfully identified in this study. Webb26 maj 2024 · 95 Guanidium hydrochloride solution (8 M concentration), iodoacetamide (IAM), dithiothreitol, 96 and hydrochloric acid microdialysis cassettes and devices (10 K MWCO) were purchased ... 105 for 30 min at 37°C, followed by alkylation of free thiols with 70 mM IAM for 30 min at room 106 temperature in the dark.
Webb11 apr. 2024 · An aliquot of 200 mM iodoacetamide (IAM) in 50 mM AmBic was added to each sample to yield a final IAM concentration of 20 mM (in the presence of a 2× molar excess of DTT); the mixture then was incubated in the dark at room temperature for 30 min to permit the alkylation reaction to proceed. WebbThe first alkylation step involved incubating CprK with 50 m m IAM (final concentration) for 15 min at room temperature. The IAM stock solution was prepared by adding 100 mg of IAM to a solution containing 0.5 m sodium acetate, 2 m m Na-EDTA and incubating at 65 °C until the crystals were dissolved.
Webbalkylation of non-cysteine residues(1-17 %, Fig. 1, upper chart, orange bars). In contrast to IAA, CAA shows only minor over-alkylation, even at 50 mM and 37 °C (Fig. 1, lower chart, orange bars). Based on the obtained data it can be concluded that CAA is – compared to IAA – a superior reagent for cysteine alkylation in proteomics workflows.
