The Collagen Interaction Discovery Platform
Collagen is the most abundant structural protein in the extracellular matrix,
but it is far more than a passive scaffold. Its triple-helical structure encodes a large number of discrete binding motifs that regulate interactions with cell receptors,
enzymes, immune molecules, and pathogens.
These interactions control fundamental biological processes including cell adhesion, differentiation,
tissue remodeling, immune modulation, and host-pathogen recognition.
The Collagen Interaction Discovery Platform enables researchers to study these interactions at sequence-level resolution.
At the core of the platform are triple-helical collagen peptides that faithfully reproduce defined regions of native collagen molecules. By presenting specific collagen motifs in a controlled format, these peptides allow systematic analysis of how individual collagen sequences engage biological receptors and influence cellular responses.
The platform combines two complementary components:
1. Collagen Ligands Collection (CLC)
Sequence-defined libraries of triple-helical collagen peptides representing the interaction landscape of selected collagens.
These collections enable screening and mapping of binding sites for cells, receptors, antibodies, enzymes, or pathogens.

2. Targeted Receptor Ligands
A portfolio of defined collagen motifs that selectively engage key collagen receptors, including:
- Collagen-binding integrins,
- Discoidin Domain Receptors (DDR1 and DDR2),
- Immune receptors such as LAIR1/2,
- OSCAR, involved in osteoclast differentiation,
- GPVI and related collagen-recognition systems.

Together, these tools allow researchers to move beyond bulk collagen materials and investigate collagen biology with molecular precision.
By enabling sequence-resolved collagen interaction profiling, the platform supports a wide range of applications, including:
- Stem cell microenvironment engineering,
- Biomaterial and scaffold design,
- Organoid and tissue model optimization,
- Host-pathogen interaction studies,
- Immunology and inflammation research,
- Receptor biology and drug discovery.
The Collagen Interaction Discovery Platform bridges collagen sequence information and biological function,
enabling researchers to design experiments and materials based on defined molecular interactions rather than empirical matrix composition.
