DSG (Disuccinimidyl Glutarate) from MtoZ Biolabs is a high-purity, amine-reactive homobifunctional crosslinker designed for covalent stabilization of protein-protein interactions and biomolecular conjugation under controlled experimental conditions.
Product Overview
In protein interaction and conjugation studies, crosslinker design directly influences interaction capture and downstream analysis. Among commonly available crosslinking reagents, several inherent limitations are often encountered:
1. Spacer Length Not Suitable for Short-Range Interactions
Crosslinkers with excessively long or poorly defined spacer arms may fail to accurately stabilize closely associated protein interactions.
2. Inconsistent Amine Reactivity
Variability in NHS ester stability and reagent purity can lead to uneven reactivity toward lysine residues and protein N-termini, affecting reproducibility.
3. Structural Perturbation of Protein Complexes
Some crosslinkers introduce unnecessary structural constraints, complicating interpretation in interaction mapping or structural studies.
4. Limited Downstream Compatibility
Certain chemical properties may interfere with electrophoresis, immunodetection, or mass spectrometry-based workflows.
