    Protein per Gram Powder
    See Label.
    Concentration for 1 unity OD at 280 nm
    1.132 mg/ml
    Physical Appearance
    Sterile Filtered White lyophilized (freeze-dried) powder.
    Purity
    > 96 % by SDS-PAGE and SEC-HPLC analyses.
    Specificity
    The recombinant Protein L is a genetically engineered protein containing 5 IgG-binding regions of protein L. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the recombinant Protein L to ensure the maximum specific IgG binding. The recombinant Protein L is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein L binds to human, mouse, rat and pig IgG.
    Endotoxin Level
    Less than 0.1 EU/μg of Protein L-Cys as determined by LAL method.
    Formulation
    Lyophilized from additive free solution.
    Stability & Storage
    Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
    - 12 months from date of receipt, -20 to -70 °C as supplied.
    - 1 month, 2 to 8 °C under sterile conditions after reconstitution.
    - 3 months, -20 to -70 °C under sterile conditions after reconstitution.
    Reconstitution
    Dissolve in distilled water or saline.
    Background
    Recombinant Protein L contains 5 kappa-binding domain. Protein L has the unique ability to bind through kappa light chain interactions without interfering with the antibody’s antigen-binding site. This gives Protein L the ability to bind a wider range of Ig classes and subclasses than other antibody-binding proteins.
