As mentioned in the Preparation Note on the product webpage, the collagen is "prepared by a modification of the pepsin extraction and salt fractionation method of Niyibizi, C., et al., J. Biol. Chem., 259, 14170 (1984). It is an acid soluble collagen that can be dissolved in water with acetic acid added to pH 3.0 (5 mg/mL), yielding an opalescent, colorless solution.
The presence of Atelo or Telo collagen is not determined.

Application
This product is intended to produce thin layer coatings on tissue culture plates to facilitate attachment of anchorage-dependent cells, recommended for use at 6-10 μg/cm2. It is NOT intended for production of 3-D gels. Type I collagen is often used in cell culture as an attachment substratum with myoblasts, spinal ganglia, hepatocytes, embryonic lung, heart explants, fibroblasts, endothelial cells, and islet cells have all been cultured successfully on films or gels of type I collagen. Collagen type I may also be used in research of Idiopathic pulmonary fibrosis (IPF), studies on the effect of ER stress IPF on lung fibroblasts. Collagen in acidic solution can produce three dimensional scaffolding with use in bioengineering and cell culture applications.
Biochem/physiol Actions
Type I collagen is a component of skin, bone, tendon, and other fibrous connective tissues.
Preparation Note
Prepared by a modification of the pepsin extraction and salt fractionation method of Niyibizi, C., et al., J. Biol. Chem., 259, 14170 (1984). It is an acid soluble collagen that can be dissolved in water with acetic acid added to pH 3.0 (5 mg/mL), yielding an opalescent, colorless solution.
Other Notes
Il collagene è classificato in diversi tipi strutturalmente e geneticamente distinti. Sigma utilizza la nomenclatura proposta da Bornstein e Traub. Occorre prestare attenzione a non confondere le denominazioni delle tipologie Sigma con le classificazioni del collagene universalmente riconosciute.
All collagen molecules are composed of three polypeptide chains arranged in a triple helical conformation, with a primary structure that is mostly a repeating motif with glycine in every third position and proline or 4-hydroxyproline frequently preceding the glycine residue. Type I collagen differs from other collagens by its low lysine hydroxylation and low carbohydrate composition.
