Protein A Sepharose
Product Overview
Contents:
Supplied as a 50% slurry in 20 % Ethanol/H2O.
Features:
High binding capacity = Binding of IgG ≥16 mg human or rabbit IgG/ml Protein A-Sepharose.
Minimal Leaching of the Ligand
Flow Rate Tested* = 2.07 ml/min.
*Test condition: = Calculations based on the time required to pass 18 ml of water through 2 ml settled beads (column diameter 1.5 cm).
Usage = Reusable for up to 10 times without significant loss of binding capacity.
Applications:
- Purification of monoclonal and polyclonal antibodies from culture media, serum, ascites fluid or hybridoma supernatants.
- Isolation of antibody/antigen complexes in immunoprecipitation experiments, since only the Fc region is involved in antibody binding and the Fab region is available for binding antigen.
Description:
Protein A-Sepharose beads are prepared by covalently coupling recombinant Protein A to 6% cross-linked Sepharose beads. 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 ≥ 16 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.
