Product Description
Collagen type I is a fibrillar extracellular matrix protein composed primarily of two α1(I) chains (COL1A1) and one α2(I) chain (COL1A2), forming a triple-helical structure with an approximate molecular weight of ~300 kDa (heterotrimer). It is the principal structural component of connective tissues such as skin, tendon, bone, and interstitial stroma, where it provides tensile strength and mechanical integrity.
In biological systems, Collagen I is secreted by fibroblasts, myofibroblasts, and other mesenchymal cells and assembled into highly ordered fibrils within the extracellular matrix. Increased deposition, reorganization, or alignment of Collagen I is a hallmark of fibrosis, tissue stiffening, wound repair, and pathological remodeling. Immunostaining reveals characteristic fibrillar or network-like extracellular patterns that provide spatial insight into matrix architecture and tissue mechanics.
The BioDeviceLab Collagen I Antibody is supplied as a purified monoclonal antibody to support flexible assay design. It can be used with secondary antibodies for indirect detection, adapted for custom labeling strategies, or integrated into biosensor, biodevice, and matrix-on-chip workflows. The antibody is compatible with conventional culture systems as well as 3D matrices, organoids, and microfluidic or organ-on-chip platforms.
Intended Use
This product is intended for research applications including
• Extracellular matrix visualization and characterization
• Fibrosis and tissue remodeling studies
• Immunofluorescence and immunocytochemistry imaging
• Organoid, spheroid, and 3D culture matrix analysis
• Tissue engineering and regenerative medicine research
• Cell–matrix interaction studies
• Biosensor, biodevice, and assay biological validation
• Multiplex phenotyping of stromal and matrix states
Principle of Operation
Collagen I is localized within the extracellular matrix. Binding of the antibody following appropriate fixation enables
• Visualization of fibrillar collagen networks by immunofluorescence
• Assessment of matrix density, organization, and alignment
• Correlation of ECM remodeling with cellular phenotypes or mechanical cues
• Integration of matrix readouts with cellular or signaling markers

Sample Volume and Typical Usage
Recommended sample volumes depend on assay format and platform and should be optimized experimentally. Common working ranges are summarized below.
Immunofluorescence / Immunocytochemistry
• Typical staining volume: 50–200 µL per sample
• Applicable to coverslips, chamber slides, well plates, tissue sections, and on-chip chambers
• Extended incubation may be required for dense matrices
Organoid and 3D Culture Staining
• Typical staining volume: 100–500 µL per sample
• Volume depends on matrix composition and construct thickness
• Prolonged incubation improves fibrillar labeling
Microfluidic and Biodevice Platforms
• Typical staining volume: 10–100 µL per device
• Volume depends on channel geometry and matrix volume
• Flow-assisted staining may enhance uniform penetration
General notes
• Antibody concentration is more critical than absolute volume
• Maintain consistent antibody-to-matrix ratios
• Optimization is recommended for each assay format and platform
