Purity: Greater than 98.0% as determined by: (a) Analysis by HPLC. (b) Analysis by SDS-PAGE.
Endotoxin Levels: Not Determined. Testing recommended prior to use in cell culture and can be performed upon request.
Buffer: SPA protein was lyophilized with no additives.
Storage Conditions: Lyophilized SPA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SPA should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

| General Description of Recombinant other SPA-Cys. | |
| SPA-Cys Recombinant produced in E. Coli is a single non-glycosylated polypeptide chain with a Cys on C-terminus. SPA-Cys is comprised of 5 IgG-binding domains E-D-A-B-C aligned in series containing 297 amino acids and having a molecular mass of 33.5kDa containing little or no carbohydrate. Cell wall binding region, cell membrane binding region and albumin binding region were removed to ensure the highest specific IgG binding. | |
