The 96-Well C-Trap Asp-N Digestion and Desalting Kit launched by MtoZ Biolabs is designed for batch protein samples. It performs Asp-N digestion and desalting in parallel and helps improve the efficiency of medium- to high-throughput sequence coverage analysis.
Product Overview
Medium- to high-throughput Asp-N digestion samples exhibit wide variation in protein abundance and pronounced differences in lysis backgrounds, and are often accompanied by residual salts and detergents. These characteristics pose specific challenges to the stability of Asp-N digestion and desalting following protein extraction.
1. Amplified Matrix Differences
When residual salt levels, detergents, and denaturants are inconsistent, traditional conditions cannot synchronously calibrate the reaction environment across wells, readily leading to differences in digestion rates and localized missed cleavages.
2. Loss Introduced by Open Handling
Stepwise workflows involve multiple transfers and well changes. In 96-well batch processing, adsorption losses and cross-contamination are more likely to occur, affecting peptide recovery.
3. Instability of Acidic Peptides
Asp-N products tend to be more acidic. Under conventional desalting and elution conditions, mismatches in binding and elution windows are more likely to occur, resulting in unstable recovery.
4. Elevated Background Affects MS Performance
Residual salts and impurities can increase ion suppression and raise the baseline, leading to fluctuations in spray stability and peak shape and widening inter-well signal differences.
Advantages
1. 96-Well Parallel Processing
The MtoZ Biolabs' 96-well C-trap Asp-N digestion and desalting kit enables batch workflows to be executed within a unified plate, reducing the accumulation of inter-well environmental differences and better matching medium- to high-throughput timelines.
2. Optimized Asp-N Cleavage System
Reaction conditions are optimized around Asp-N cleavage characteristics, helping to generate more consistent peptide output and reduce variability associated with missed cleavages.
3. In-Plate Continuity to Minimize Loss
Digestion and desalting are performed sequentially within the plate, reducing intermediate transfers and open handling steps and lowering the risk of sample loss and contamination.
4. Integrated Desalting for LC-MS/MS Compatibility
The workflow simultaneously attenuates the impact of salts and interfering components, reduces ion suppression and background noise, and improves the stability and comparability of batch LC-MS/MS measurements.
