Protein L-coupled Magnetic Beads (recommended for MPCLIA)

The Protein L-coupled Magnetic Beads are 2.8 µm superparamagnetic particles covalently coupled to a highly pure form of Protein L. The beads can be used to capture the antibodies in Chemiluminescence procedures. The Protein L is a 45 kDa surface protein, and can bind almost all antibody types, including IgG, IgM, IgA, IgE and IgD. It binds to antibodies with appropriate Kappa light chains such as VkI, VkIII and VkIV, whereas no binding occurred with antibodies of the VkII or with any Lambda light chains. The Protein L-coupled Magnetic Beads is easy to capture the most antibodies, and the bounded antibody have no activity lost, this ready to use products could greatly save your protein coupling time and hassle, and help us get the best performance and highly reproducible results.

The Protein L-coupled Magnetic Beads is used to capture the most antibodies, it can combination with Acridinium ester markers in chemiluminescence technology. The Acridinium ester markers such as Streptavidin-Acridinium ester can capture the biotinylated proteins or molecules, this allows detection of Fc receptors and antibody binding.

Upon receipt, please store the Beads at -20°C. The shelf life is 1 year at -20 °C. Please avoid more than 3 freeze-thaw cycles once reconstitution, immediate use after reconstitution is highly recommended.
