- RPPB4793
Description
| Product Name: | SPA-Cys Long Recombinant Protein |
| Product Code: | RPPB4793 |
| Size: | 100mg |
| Target: | SPA-Cys Long |
| Synonyms: | Immunoglobulin G-binding protein A, IgG-binding protein A, Staphylococcal protein A, SPA. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | SPA protein was lyophilized with no additives. |
| Solubility: | It is recommended to reconstitute the lyophilized SPA in sterile 18M?-cm H2O not less than 0.1mg/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | 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. |
| Purity: | Greater than 97.0% as determined by analysis by SDS-PAGE. |

Protein A is a cell wall component produced by several strains of Staphylococcus aureus. The recombinant Protein A is genetically engineered protein and holds 5 IgG-binding regions of protein A. Recombinant Protein A functions basically the same as native Protein A and is perfect for purification of polyclonal or monoclonal IgG antibodies. Protein A binds to human IgG1, IgG2 and IgG4, mouse IgG2a, IgG2b and IgG3 and rat IgG2c. Protein A also binds to total IgG from rabbit, pig, dog, cat, and guinea pig.
SPA-Cys long 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 423 amino acids and having a molecular mass of 46.7kDa containing little or no carbohydrate.�
