Protein L Gold Conjugate: A Superior Detection Tool

The Protein L Gold Conjugate is a cutting-edge reagent designed for sensitive detection of human and mouse antibodies containing kappa light chains. This high-quality conjugate offers an array of benefits that make it a superior choice for various applications. With a gold nanoparticle core size of 15nm and an absorbance peak at 520nm, this conjugate ensures optimal performance in immunoblotting, lateral flow assays, light microscopy, and electron microscopy. Its unique conjugated protein, Recombinant Protein L from P. magnus produced in E. coli, provides exceptional binding capabilities to a broad range of immunoglobulin classes, including IgG, IgM, IgA, IgE, and IgD.

Key Features and Specifications

The Protein L Gold Conjugate is available in two optical densities: OD=3 and OD=10, allowing users to select the appropriate concentration for their specific needs. With a working dilution range of 1:5 to 1:100, this conjugate offers flexibility and ease of use. Supplied in a storage buffer consisting of 1XPBS (pH 7.4), 20% glycerol (v/v), and 1% BSA, the conjugate maintains stability and performance. Its unique advantages include its ability to bind to a broader range of immunoglobulin classes than Protein A or Protein G, as well as its specificity for human and mouse antibodies, making it ideal for detecting antibodies produced in tissue culture media containing Fetal Bovine Serum (FBS).

Applications and Benefits

The Protein L Gold Conjugate is a versatile tool suitable for a wide range of applications. Its high sensitivity and specificity make it an excellent choice for detecting antibodies in serum, tissue culture media, and ascites. The conjugate's ability to bind to single-chain variable fragments (scFv) and Fab fragments containing kappa light chains further expands its utility. By not binding to goat or bovine IgG, this conjugate ensures specific detection of human and mouse antibodies, making it an ideal choice for researchers working with FBS-containing media. With its convenient storage and stability, the Protein L Gold Conjugate is a reliable and efficient reagent for your research needs.
