| Description : |
Collagen alpha-1(XVIII) chain is a protein that in humans is encoded by the COL18A1 gene. This gene encodes the alpha chain of type XVIII collagen. This collagen is one of the multiplexins, extracellular matrix proteins that contain multiple triple-helix domains (collagenous domains) interrupted by non-collagenous domains. The proteolytically produced C-terminal fragment of type XVIII collagen is endostatin, a potent antiangiogenic protein. Mutations in this gene are associated with Knobloch syndrome. The main features of this syndrome involve retinal abnormalities so type XVIII collagen may play an important role in retinal structure and in neural tube closure. Two transcript variants encoding different isoforms have been found for this gene. |

| Formulation : |
Lyophilized from a 0.2 µm filtered solution in PBS. |
| Bio-activity : |
Measured by its ability to inhibit the FGF basic-dependent proliferation of HUVEC human umbilical vein endothelial cells. The ED50 for this effect is typically 0.3-1.5 µg/mL in the presence of 20 µg/mL of Goat Anti-Mouse Endostatin Antigen Affinity-purified Polyclonal Antibody. |
