General Description of Recombinant other SPA 33.4kDa.
SPA Recombinant produced in E. Coli is a homodimeric non-glycosylated polypeptide chains comprised of 5 IgG-binding domains E-D-A-B-C aligned in series containing 296 amino acids and having a molecular mass of 33.4kDa 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.

Purity: Greater than 97.0% 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.
