Advantages of Protein L Gold Conjugates
- Sensitive probe for detection of human and mouse antibodies containing kappa light chains in samples such as serum, tissue culture media and ascites among others.
- Binds to a broader range of immunoglobulin classes than Protein A or Protein G. These include IgG, IgM, IgA, IgE and IgD.
- Binds single-chain variable fragments (scFv) and Fab fragments that contain kappa light chains.
- Does not bind goat or bovine IgG which makes it ideal for the specific detection of human and mouse antibodies produced in tissue culture medium containing Fetal Bovine Serum (FBS).
- Store undiluted in storage buffer at 2-8 degree Celsius. Stable for 4 months if stored as specified.
- Storage of conjugate at working dilution may result in performance loss.
