EcoMag™ Protein L Magnetic Beads are silica-based superparamagnetic beads covalently conjugated with recombinant protein L (Purity: >80%) on the surface. Unlike protein A, protein G or protein A/G, protein L binds kappa light chains (i.e., k chain of the VL domain) instead of Fc region (i.e., heavy chain) of immunoglobulins. Therefore, protein L beads not only bind IgG, but also other classes of Ig including IgM, IgA, IgE and IgD, and single chain variable fragments (ScFv) and Fab fragments. . The Beads are specifically designed, tested and quality controlled for use in quick and efficient one-step purification of monoclonal antibodies from ascites or culture supernatants because it does not bind bovine immunoglobulins
• Quick, Easy and one-step high-throughput procedure; eliminates columns or filters, or laborious repeat of pipetting or centrifugation
• Binds IgG, IgM, IgA, IgE and IgD
• Binds single-chain variable fragments (ScFv)
• Not bind bovine, goat or sheep Igs
• Ultra low non-specific binding thanks to the beads' hydrophilic surface
• High binding capacity
• Scalable - easily adjusts for sample size and automation
• Low costPlease contact us at for specific academic pricing.
