MtoZ Biolabs employs multiple advanced technologies and analytical platforms to launch the protein interaction profiling service enabling systematic characterization of interaction features between proteins and diverse classes of molecules. This service is applicable to functional association studies and interaction network construction, providing a reliable data foundation for the systematic analysis of complex biological systems.
What Is Protein Interaction?
Protein interaction refers to the specific or condition-dependent binding relationships formed between proteins and a wide range of biological molecules, including other proteins, nucleic acids, small molecules, and lipids. These interactions constitute a fundamental basis for functional execution and regulatory network organization within cells. Such interactions are broadly involved in signal transmission, structural assembly, metabolic regulation, and information integration. Systematic analysis of protein interactions helps elucidate functional associations among molecules and their coordinated roles within biological systems, providing critical insights into complex biological processes.

Protein Interaction Profiling Service at MtoZ Biolabs
1. Protein-Protein Interaction Analysis
Used to identify and validate whether direct or indirect binding relationships exist between proteins, helping to construct protein interaction networks and clarify potential functional associations.
2. Protein-Metabolite Interaction Analysis
By detecting the binding of proteins to specific metabolites, this analysis evaluates interaction characteristics and provides a basis for understanding the roles of proteins in metabolic regulation.
3. Protein-DNA Interaction Analysis
Applied to examine protein binding behavior to specific DNA sequences, assisting in the confirmation of DNA-binding properties and related regulatory associations.
4. Protein-RNA Interaction Analysis
Used to characterize binding relationships between proteins and RNA, supporting systematic analysis of RNA-binding proteins and their associated RNA targets.
Technical Platforms for Protein Interaction Profiling Service
1. Protein Microarray
By immobilizing proteins or related molecules at high density on a solid-phase chip, protein microarrays enable parallel detection of multiple interaction events and are well suited for high-throughput interaction screening and profiling.
2. Yeast Two-Hybrid (Y2H)
Based on an intracellular expression system in yeast, this method screens for direct protein–protein interactions and is commonly used to identify novel interaction partners and construct interaction networks.
3. Glutathione S-Transferase Pull-Down Assay
This assay uses the specific binding between a GST tag and glutathione resin to enrich interacting proteins and is applied to verify whether direct binding exists between proteins.
4. Co-Immunoprecipitation (Co-IP)
Through the use of specific antibodies to enrich a target protein together with its associated binding partners, this approach detects protein interaction states under near-native conditions.
5. Mass Spectrometry (MS)
Mass spectrometry is used to identify and characterize proteins or other binding components within interaction systems, supporting systematic confirmation of interaction partners.
