| Introduction | |
| SPARC, an acronym for “secreted protein, acidic and rich in cysteine”, is also known as osteonectin or BM-40. It is the founding member of a family of secreted matricellular proteins with similar domain structure. The 303 amino acid, 43 kDa protein contains a 17 aa signal sequence, an N-terminal acidic region that binds calcium, a follistatin domain containing Kazal-like sequences, and a C-terminal extracellular calcium (EC) binding domain with two EF-hand motifs. SPARC is produced by fibroblasts, capillary endothelial cells, platelets and macrophages, especially in areas of tissue morphogenesis and remodeling. SPARC shows context-specific effects, but generally inhibits adhesion, spreading and proliferation, and promotes collagen matrix formation. For endothelial cells, SPARC disrupts focal adhesions and binds and sequesters PDGF and VEGF. SPARC is abundantly expressed in bone, where it promotes osteoblast differentiation and inhibits adipogenesis. | |

| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4. | |
| Stability | |
| Lyophilized SPARC although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Secreted Protein Acidic & Rich in Cysteine should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles . | |
| Purity | |
| Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. | |

| Biological Activity | |
| The ED50 as determined by its ability to inhibit the cell growth of Mv1Lu mink lung epithelial cells is < 3.0 µg/mL, corresponding to a specific activity of > 333 IU/mg. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized SPARC in sterile 18MΩ-cm H 2 O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Precautions | |
| SPAG7 Human is for research use only and not for use in diagnostic or therapeutic procedures. | |
