Applicazioni
Type IV collagen has been found to play a key role in angiogenesis, neurological diseases and metastasis. 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.
Azioni biochim/fisiol
During development, collagen IV is ubiquitously distributed in BMs. During the maturation process, this network gets partially replaced in a remarkably tissue specific manner, defining BM structure and function. Collagen IV has been shown to bind to platelets, hepatocytes, keratinocytes, endothelial, mesangial, pancreatic cells and some tumor cells.
Tissue injury in the autoimmune disease Goodpasture syndrome is due to pathogenic autoantibodies targeting the Collagen IV α3 chain . Mutations in COL4A5 are associated with Alport syndrome.

Componenti
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 IV collagen occurs only in the basement membranes and contains up to six genetically distinct a-chains.
Avvertenza
Store this product at -20°C. It will retain activity for 2 years under these conditions.
Nota sulla preparazione
This product is supplied as a solution in 0.5 M acetic acid. It can be used to coat tissue-culture surfaces to promote cell attachment. The amount used in these applications is dependent on the cell type, plastic ware and incubation time. A recommended amount is 0.5-5 μg/cm2. It was prepared by pepsin extraction and chromatographic purification.
Altre note
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.

Topography-guided laser refractive surgery regularizes the front corneal surface irregularities to achieve the desired refractive outcome. This is particularly applicable in highly aberrated corneas, where wavefront aberrometry is often not possible. This article aims to review the recently published results
