Description
| Product Name: | Protein-L Recombinant Protein |
| Product Code: | RPPB4310 |
| Size: | 10mg |
| Target: | Protein-L |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Protein-L was lyophilized without any additives. |
| Solubility: | It is recommended to reconstitute the lyophilized Protein-L in sterile 18M-cm H2O not less than 0.1mg/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | Lyophilized Protein-L although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Protein-L 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: (a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE. |

The Recombinant Protein L is comprised of 5 kappa-binding domains. Protein L has the exceptional ability to bind through kappa light chain interactions without hindering with the antibody�s antigen-binding site. This gives Protein L the capacity to bind a broader range of Ig classes and subclasses than other antibody-binding proteins. The recombinant Protein L is perfect for purification of polyclonal or monoclonal IgG antibodies. Protein L binds to IgG from humans, mice, rats and pigs.
Recombinant Protein-L produced in E.Coli is a single non-glycosylated polypeptide chain fused with a 6�His tag at N-terminus. Protein-L is comprised of 5 IgG-binding regions of protein L (B1-B2-B3-B4-B5) containing 372 amino acids in total and having a molecular mass of 41.5kDa, however, it migrates with an apparent molecular mass of 46kDa on SDS-PAGE. Cell wall binding region, cell membrane binding region and albumin binding region have been eliminated from the recombinant Protein-L to guarantee the maximum specific IgG binding.
