General description

Collagen is a widely expressed protein in the body. There are 20 different types of collagen in human tissue. Type I collagen is the abundant bone protein. It constitutes ~90% of bone organic matter.
Collagen is classified into a number of structurally and genetically distinct types. We use the nomenclature proposed by Bornstein and Traub. Do not confuse Sigma type designations with recognized collagen classification types.
Collagen terminology using the Bornstein and Traub designation originates from the reference; Bornstein, P. and Traub, W. The Proteins, (1979) 4, 411-605

Application

Bovine achilles tendon collagen was used in a study of plant extracts as inhibitors of MMP-collagenases, the putative active agents in the breakdown of cartilage in osteoarthritis and rheumatoid arthritis.
Collagen from bovine achilles tendon is suitable for use in:
  • the detection of collagenase activity
  • as a reference sample in the thermal analysis study of human bone using differential scanning calorimetry, thermogravimetry, gas chromatography and Fourier transform infrared spectroscopy
  • as a substrate for developing a simple assay for determining collagen degradation in vitro
  • a study to examine the binding activity of the integral glycoprotein dipeptidyl peptidase IV to insoluble type I collagen by solid-phase enzyme-linked immunosorbent assay
Collagen from bovine Achilles tendon is a naturally occurring protein in the form of elongated fibrils. It may be used in studies of the fibrocartilaginous zone, which the collagen must first pass through before inserting into the calcaneus. It may also be used in studies of growth factor effects on collagen content and cross-linking during Achilles tendon healing.

Biochem/physiol Actions

Collagen from bovine Achilles tendon is a naturally occurring protein in the form of elongated fibrils. It may be used in studies of the fibrocartilaginous zone, which the collagen must first pass through before inserting into the calcaneus. It may also be used in studies of growth factor effects on collagen content and cross-linking during Achilles tendon healing.
Collagen is an insoluble fibrous protein that is part of the extracellular matrix and the connective tissue. It is responsible for the ability of the tissues to withstand stretching. The long precursors called procollagens are synthesized and assembled in the ER, secreted into the extracellular space and processed to form collagen fibres. The different types of collagen are composed of molecules containing three polypeptide chains arranged in a triple helical conformation varying slightly in the amino acid sequence. The primary structure is a repeating motif with glycine in every third position preceded frequently with a proline or 4-hydroxyproline residue.

Preparation Note

Prepared by the method of Einbinder, J. and Schubert, M., J. Biol. Chem., 188, 335 (1951).

Reconstitution

This product is an insoluble collagen preparation. It is insoluble in water, aqueous buffers, dilute acid, and organic solvents. For use as a substrate in collagenase assays, this collagen can be prepared as a suspension in 50 mM TES buffer, pH 7.4 with 0.36 mM calcium chloride.
