Peptides With Laminin Activity

Peptides with laminin activity, including YIGSR, are claimed. These peptides block angiogenesis, alter the formation of capillary structures by endothelial cells, prevent the formation of excess blood vessels in tissue and inhibit in vivo tumor cell colonization of tissues. These peptides can be used, among other things, to inhibit metastasis.

Potential Commercial Applications: Competitive Advantages:
  • cancer therapeutic
  • research reagent
  • encourage cell adhesion
  • inhibits metastasis and angiogenesis
