The Tyrosine-Phosphorylated Peptide Enrichment Kit launched by MtoZ Biolabs is specifically designed for low-abundance pTyr peptides, enabling highly specific enrichment and supporting research on signaling pathways and phosphorylation regulation.
Product Overview
Tyrosine phosphorylation typically occurs at a low frequency, exhibits rapid dynamic changes, and is often derived from complex peptide mixtures generated from digested cells or tissues, creating distinct challenges for the isolation and detection of these peptides:
1. Extremely Low Modification Abundance
Tyrosine phosphorylation accounts for only a small fraction of total phosphorylation events, and the corresponding peptides are easily masked by large numbers of unmodified peptides or serine- and threonine-phosphorylated peptide signals.
2. Highly Transient Modification Events
Tyrosine phosphorylation often occurs rapidly under stimulation and is quickly dephosphorylated, making the authentic modification state prone to loss during sample processing.
3. High Specificity Requirements
Tyrosine-phosphorylated peptides must be strictly distinguished from other phosphorylated peptides, and conventional phosphopeptide enrichment strategies often fail to meet the required selectivity.
4. Pronounced Variability in Sample Background
Samples from different sources vary substantially in protein composition and stimulation status, increasing the difficulty of maintaining consistency in enrichment performance.
Advantages
✅ Targeted Enrichment
The enrichment system of the tyrosine-phosphorylated peptide enrichment kit from MtoZ Biolabs is designed around the characteristics of tyrosine phosphorylation, enabling precise capture in complex backgrounds.
✅ Improved Interpretability of Enrichment Results
The optimized workflow reduces the inclusion of non-target peptides in the enriched fraction, resulting in more concentrated and clearer signals for subsequent analysis.
✅ Applicable to Multiple Experimental Systems
The kit can be applied to digested peptide samples from different sources and treatment conditions, demonstrating good stability and reproducibility.
✅ Support for Multiple Validation Strategies
The enriched products can be directly applied to LC-MS/MS, Western blot, and immuno-enrichment validation in downstream analytical workflows.
