The C-Trap Glu-C Digestion and Desalting Kit launched by MtoZ Biolabs is specifically designed for Glu-C digestion of complex protein samples. By integrating digestion and desalting into a single workflow, it reduces sample loss and helps improve sequence coverage analysis.
Product Overview
Complex protein samples typically feature complicated matrix backgrounds, substantial buffer carryover, and strong protein conformational heterogeneity, which pose specific challenges for Glu-C directed enzymatic digestion and desalting:
1. Matrix Interference Affecting Digestion Efficiency
Residual salts, detergents, and denaturants can alter Glu-C cleavage kinetics, leading to incomplete digestion or uneven site coverage.
2. Sample Loss Introduced by Stepwise Handling
Multiple tube changes, transfers, and open handling steps can introduce adsorption loss and contamination, making low-abundance peptides more difficult to retain.
3. Instability of Acidic Peptide Behavior
Peptides generated by Glu-C are enriched in acidic residues and may exhibit variable binding efficiency under conventional desalting and elution conditions, resulting in unstable recovery.
4. Elevated Background Compromising Mass Spectrometric Performance
Residual salts and small-molecule contaminants can cause ion suppression and increased background noise, negatively affecting LC-MS/MS sensitivity and reproducibility.
Advantages
✅ Integrated In-Tube Workflow
The MtoZ Biolabs' C-trap Glu-C digestion and desalting kit enables sequential digestion and desalting within the same tube, reducing tube opening and transfers and lowering the risk of sample loss and contamination.
✅ More Controllable Glu-C Cleavage
The reaction system is optimized around Glu-C cleavage characteristics, supporting more stable peptide generation in complex matrix backgrounds and reducing missed cleavages and sequence coverage bias.
✅ More Direct Desalting and Interference Removal
Built-in desalting simultaneously attenuates the impact of residual salts, detergents, and buffers, reducing ion suppression and background noise and improving signal stability during LC-MS/MS analysis.
✅ More Consistent Batch Results
Standardized reaction and washing paths reduce operator-dependent variability and batch effects, making the kit well suited for proteomics studies requiring high reproducibility and comparability.
