Recombinant Protein-L produced in E.Coli is a single non-glycosylated polypeptide chain fused with a 6×His tag at N-terminus and a Cys on C-terminus. Protein-L is comprised of 5 IgG-binding regions of protein L (B1-B2-B3-B4-B5) containing 373 amino acids in total and having a molecular mass of 41.6kDa, 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.

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).
Formulation
Protein-L was lyophilized without any additives.
