The 384-Well C-Trap Asp-N Digestion and Desalting Kit launched by MtoZ Biolabs is designed for large-batch protein samples. It standardizes Asp-N digestion and desalting conditions, helping to improve the efficiency of large-scale sequence coverage analysis.
Product Overview
Ultra-high-throughput Asp-N digestion samples typically have smaller per-well volumes and more dispersed sample sources. Under traditional stepwise workflows, these factors are more likely to accumulate as inter-well variability, posing specific challenges to the efficiency of Asp-N digestion and the stability of desalting following protein extraction.
1. Micro-Scale Stepwise Loss
Traditional workflows require multiple tube openings, transfers, or consumable changes between digestion and desalting. Under low-volume conditions in 384-well formats, adsorption residues and irreversible losses are more likely to occur, making low-abundance peptides harder to retain.
2. Matrix Differences Lead to Missed Cleavages
Differences in residual salts, detergents, and buffer systems across wells are more pronounced. Traditional conditions struggle to unify the reaction environment, readily causing fluctuations in digestion kinetics and localized missed cleavages, leading to unstable peptide output.
3. Inconsistent Operation Leads to Deviation
In ultra-high-throughput workflows, differences in dispensing order, mixing efficiency, and incubation time windows are more common. Traditional stepwise processes make it difficult to maintain consistent timing, amplifying inter-well variability.
4. Difficulty in Balancing Desalting and Recovery
Asp-N products tend to be more acidic. Under conventional desalting and elution conditions, insufficient binding or uneven elution is more likely to occur, while residual salts can also induce ion suppression, compromising consistency during MS analysis.
Advantages
✅ 384-Well Parallel Processing for Higher Throughput
The MtoZ Biolabs' 384-Well C-Trap Asp-N Digestion and Desalting Kit enables one-run parallel processing of large batches of samples, reduces repetitive handling, and better matches the pace of large-scale experiments.
✅ Optimized Asp-N Reaction System
Reaction conditions are optimized around Asp-N cleavage characteristics, helping to achieve more controllable cleavage output under complex lysis backgrounds and reducing variability associated with missed cleavages.
✅ In-Plate Continuity to Minimize Loss
Digestion and desalting are performed sequentially within the same plate, reducing transfers and open handling steps and lowering the risk of sample loss and cross-contamination.
✅ Integrated Desalting for Stable MS Performance
The workflow simultaneously attenuates the impact of salts and interfering components, reduces ion suppression and background noise, and supports more stable LC-MS/MS performance in large-scale analyses.
