About this Protein |
Name | Recombinant Cys-Protein L (Recombinant Cys-Protein L; Cys-Protein L);重组蛋白-L,N端带Cys |
Synonyms | N/A |
Purity | >95% by SDS-PAGE analysis. |
Biological Activity | 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. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | Lyophilized with no additive. |
Endotoxin | Less than 0.1EU/μg of Cys-Protein L as determined by LAL method. |
Reconstitution | Dissolve in distilled water or saline. |
Category | Protein L |
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. |
