Application
Collagen from human placenta has been used to assess the bioelectric effects of quinine on airway epithelial cells, to study the selective toxicity of engineered lentvirus lytic peptides and in a particle aggregation assay for the rapid detection of fibronectin, fibrinogen and collagen receptors on Staphylococcus aureus. It has also been used in a magnesium-dependent, collagen-binding assay during characterization of human lung tumor-associated antigens.
Preparation Note
This product was prepared by a modification of the pepsin extraction and salt fractionation method of Hill, R.J. and Harper, E., Anal. Biochem., 141 (1984). It is a lyophilized powder that can be reconstituted in sterile .5 M acetic acid, PBS or water at 1 mg/mL. A PBS solution will be stable for at least one year at -20°C.
Analysis Note
An SDS polyacrylamide gel electrophoresis test run under reducing conditions consistent with basement membrane collagen yields three major bands.
Other Notes
Le collagène se classe en un certain nombre de types structurellement et génétiquement distincts. Nous utilisons la nomenclature proposée par Bornstein et Traub. Il est important de ne pas confondre les désignations utilisées par Sigma et les types de classification reconnus.
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.
Disclaimer
This product should be stored at 2-8 °C and will retain activity in these conditions for 2 years.

The plasmatic von Willebrand factor (VWF) circulates in a compact form unable to bind platelets. Upon shear stress, the VWF A1 domain is exposed, allowing VWF-binding to platelet glycoprotein Ib-V-IX (GPIbα chain). For a better understanding of the role of

Low plasma levels of protein C or protein S are associated with venous thromboembolism rather than myocardial infarction. The high coagulant activity in patients with thrombophilia with a (familial) defect in protein C or S is explained by defective protein

Patients bitten by snakes consistently manifest a bleeding tendency, in which thrombocytopenia, consumption coagulopathy, mucous bleeding, and, more rarely, thrombotic microangiopathy, are observed. Von Willebrand factor (VWF) is required for primary hemostasis, and some venom proteins, such as botrocetin (a

In haemostasis and thrombosis, platelet, coagulation and anticoagulation pathways act together to produce fibrin-containing thrombi. We developed a microspot-based technique, in which we assessed platelet adhesion, platelet activation, thrombus structure and fibrin clot formation in real time using flowing whole
