| Solubility | It is recommended to reconstitute the lyophilized Protein-L in sterile water or saline not less than 100µg/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). | ||
| Formulation | Protein-L was lyophilized with no additives. | ||
The recombinant Protein L is genetically engineered protein and holds 5 IgG-binding regions of protein L and it has the exclusive capability to bind through kappa light chain interactions without interfering with the antibodyбпs antigen-binding site. Cell wall binding region, cell membrane binding region and albumin binding region were removed to ensure the highest specific IgG binding. The recombinant Protein L is perfect for purification of polyclonal or monoclonal IgG antibodies and it binds to human, mouse, rat and pig IgG.
