MtoZ Biolabs offers specialized Protein Propionylation Analysis Service to support researchers investigating lysine propionylation across specific protein targets or complex biological samples. Through optimized enrichment methods and high-resolution LC-MS/MS, we deliver reliable qualitative identification of propionylated sites involved in metabolic regulation, chromatin remodeling and cellular stress responses. Our service provides accurate site-level information that supports pathway exploration, mechanism studies and discovery-driven research.

Overview

Protein propionylation is a lysine acylation modification formed when a propionyl group, derived from cellular metabolism, is added to the ε-amino group of lysine residues. This modification can affect protein charge, structural conformation and interaction properties, making it relevant to a range of biological processes. Propionylation has been associated with metabolic regulation, mitochondrial activity, chromatin remodeling and pathways involved in stress response and cellular adaptation.

Although present at low abundance, propionylation may exert substantial regulatory influence, particularly in contexts in which short-chain fatty acid metabolism is altered. Characterizing propionylated sites helps researchers understand how metabolic intermediates shape protein behavior, identify regulatory proteins sensitive to propionyl-CoA levels and explore pathways in which this acylation represents an important layer of control.

Protein Propionylation Analysis Service at MtoZ Biolabs

1. Targeted Protein Propionylation Analysis

We perform precise identification of propionylation sites on client-defined proteins. This service supports studies aiming to validate predicted modifications, investigate regulatory mechanisms or clarify protein-specific responses to metabolic changes.

2. Propionylation Proteomics

For discovery-focused projects, we offer proteome-wide profiling of propionylated peptides. This high-throughput workflow enables systematic identification of modification events, detection of condition-dependent changes and exploration of new regulatory targets within metabolic and stress-responsive pathways.

FAQ

Q1: What types of samples are suitable?

We accept purified proteins, immunoprecipitated proteins, cell lysates, tissue lysates, and mitochondrial or nuclear fractions. These sample types preserve endogenous propionylation and support accurate site-level identification.

Q2: How should I prepare my samples?

• Keep samples fresh or snap-frozen to prevent loss or alteration of acylation states
• Use lysis buffers compatible with immunoenrichment, avoiding detergents, high salt, or inhibitors that disrupt antibody capture
• Provide sufficient protein input (~100 µg for targeted workflows; ~500 µg for discovery-level profiling)
• When preparing IP samples, ensure high purity to facilitate confident site localization

For more information, please refer to Sample Submission Guidelines for Proteomics. If you are unsure about sample preparation, our team is available for consultation and can guide you through the process to ensure optimal results.
