产品详情

Recombinant Protein L-cys

Recombinant Protein L-cys contains 5 kappa-binding domains, and there is a C-terminal cysteine for Site-Specific Conjugation. 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.
