| Thrombospondin is a protein from platelet a-granules. It is made up of three identical subunits bound by interchain disulfides. It is secreted at sites of platelet activation and aggregation and is involved in the processes of chemotaxis, adhesion, proliferation and differentiation of leukocytes, fibroblasts, smooth muscle and endothelial cells. |

| Positive Control | HUVEC cells. |
| Cellular Localization | Secretory granules, Golgi complex, endoplasmic reticulum, extracellular matrix |
| Storage and Stability | May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
