ToxOut™ Endotoxin-Free Protein A Sepharose

• Description:

  Endo toxin free Protein A-Sepharose beads are prepared by covalently coupling recombinant Protein A to 6% cross-linked Sepharose beads under proprietary endotoxin-free conditions. BioVision Protein A (Cat. # 6500, Cat. # 6500B) is a genetically engineered protein containing five IgG-binding regions of native Protein A. The cell wall binding region, albumin binding region and other non-specific regions have been eliminated from the recombinant Protein A to ensure the maximum specific IgG binding. The coupling technique is optimized to give a higher binding capacity for IgG & minimum leaching of recombinant Protein A. The IgG binding capacity of Protein A-Sepharose is ≥ 15 mg human or rabbit IgG per ml of wet beads. Protein A-Sepharose beads display high chemical & physical stability as well as high flow rate, hydrophilicity & high gel strength. It can be used for IgG purification and immunoprecipitation. Our Endotoxin-free Protein A-Sepharose also shows ability of reducing/removing certain amount of endotoxin from serum or ascites samples.
