Protein carbonylation is the most important oxidative stress-induced post-translational modification (PTM),
characterized by irreversibility, stability, and relatively early formation. Protein carbonylation has been reported
to play an important role in coordinating various biological processes and has been associated with many diseases.
With extensive experience in protein PTM analysis and an advanced platform, Creative Proteomics
provides fast, reliable, and customized protein carbonylation analysis services to accelerate our client's
projects, including detection, analysis, and identification of carbonylated proteins and modification sites.
Protein carbonylation
Oxidative stress occurs in all organisms when the production of reactive oxygen species (ROS) severely imbalances
antioxidant defenses. Oxidative stress can lead to a variety of PTMs on proteins, including sulfhydrylation,
hydroxylation, carbonylation, and nitration. Among them, protein carbonylation is a common, non-enzymatic,
irreversible oxidative stress-induced PTM that has attracted widespread attention. Protein carbonylation has long
been well studied and considered a biomarker for measuring oxidative damage in normal and altered cell physiology.
This modification of protein has been shown to affect protein function, protein folding, protein hydrolysis and
cellular dysfunction, often leading to protein proteasomal degradation. As for human diseases, researchers have
found high levels of protein carbonylation in a great lot kind of major diseases, especially age-related diseases,
including Parkinson's disease, chronic lung disease, chronic renal failure, cataract development, and so on.

Proteomics analysis of carbonylation
Oxidative stress affects proteins and other macromolecules, and protein carbonylation is a measure of oxidative
stress in biological systems. We have developed an MS-based platform to quantify protein carbonylation and identify
their carbonylation sites. In addition, our platform includes ELISA, western blot (WB), two-dimensional gel
electrophoresis, spectrophotometric detection, affinity enrichment, and HPLC-based methods. Depending on the type of
sample, the purpose of the experimental project, and the depth of analysis, we can apply these techniques
individually or in combination. Notably, we have strong expertise in protein carbonylation site prediction by
computational methods. Based on a powerful and novel bioinformatics platform, we are able to help our clients
achieve efficient and rapid carbonylation site identification, which provides the basis and clues for analyzing the
mechanisms of physiology and disease.
