Collagen I Antibody [HRP] Summary

• Immunogen: Collagen I from human and bovine placenta (Uniprot: P02452)
• Localization: Extracellular matrix
• Specificity: Some class-specific anti-collagens may be specific for three-dimensional epitopes which may result in diminished reactivity with denatured collagen or formalin-fixed, paraffin embedded tissues. This antibody reacts with most mammalian Type I collagens and has expected cross-reactivity with Type III and negligible cross reactivity with Type II, IV, V or VI collagens. Non-specific cross-reaction of anti-collagen antibodies with other human serum proteins or non-collagen extracellular matrix proteins has not been tested.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: COL1A1
• Purity: Immunogen affinity purified

Applications/Dilutions

• Dilutions:
  • ELISA 1:3000-1:6000
  • Flow Cytometry 1:10 - 1:1000
  • Immunohistochemistry 1:50-1:200
  • Immunoprecipitation 1:100
  • Western Blot 1:3000-1:6000
• Theoretical MW: 139 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Reactivity Notes

This antibody reacts with human, bovine, and most mammalian Type I collagens with negligible cross-reactivity with Type II, III, IV, V or VI collagens

Background

Collagen I is one of the most abundant extracellular matrix (ECM) proteins in mammals and is an important structural component in connective tissues, bones, teeth, skin, heart, and lungs (1, 2). Collagen I is commonly used for biomedical purposes including providing an ECM microenvironment for cell attachment, proliferation, and mesenchymal stem cell growth and differentiation to the osteogenic lineage (1, 3, 4). Furthermore, type I Collagen hydrogels are a promising scaffold for engineering tissues and tumors (4). Collagen type I can be extracted from numerous sources including mammals, most commonly bovine and porcine, fish, amphibians, and birds (1, 4). Structurally, Collagen I is a heterotrimer comprised of two alpha-1 chains and one alpha-2 chain that together forms a triple helix (1, 3, 5). Each alpha chain is primarily formed by glycine, proline, and hydroxyproline repeats with the alpha-1 chains having a theoretical molecular weight of 139 kDa and 129 kDa for the alpha-2 chain (3). The dimeric form of Collagen I has a theoretical molecular weight of ~270 kDa while the trimeric form is >400 kDa (3, 5).

A variety of disease pathologies have been associated with mutations in or disruptions in collagen type I. Osteogenesis imperfecta, also known as brittle bone disease, is caused by autosomal dominant mutations in Collagen type I encoding genes and characterized by fragile bones and skeletal deformities (6). Ehlers-Danlos syndromes (EDS) is another disorder that affects soft connective tissue and its various clinical subtypes are associated with different mutations in Collagen I (7).

Alternative names for Collagen I includes alpha-1 type I collagen, alpha1(I) procollagen, CAFYD, COL1A1, collagen alpha 1 chain type I, collagen alpha-1(I) chain, EDSARTH1, EDSC, OI1, OI2, OI3, OI4, pro-alpha-1 collagen type 1, type I proalpha 1, and type I procollagen alpha 1 chain.
