About This Product

Leading the way in Protein A ligand manufacturing since 1985. Most of the world's commercial monoclonal antibodies are purified using native and recombinant Protein A ligands from Repligen.

■Summary

rSPA – Native Recombinant Staphylococcal Protein A Ligand is the most advanced non-mutated Protein A ligand available from Repligen. The combination of performance and purity relative to native Protein A, superior economics and supply chain security makes rSPA the automatic first choice for all new Protein A ligand applications. ・Same amino acid sequence and molecular weight as native Protein A supplied from Staphylococcus aureus ・Made with raw materials that do not contain animal substances

■Native Protein A ligand

Native Protein A is a purified ligand used to isolate IgG from crude protein mixtures. It binds with high affinity to the Fc region of IgG. When immobilized on a matrix such as Sepharose, Protein A (native) can be used to separate IgG from crude protein mixtures. Native Protein A meets the most demanding demands of pharmaceutical companies in terms of purity, reproducibility, binding capacity, specificity, and other key metrics essential to the quality of downstream processes. ・Reliable performance: Fc-specific binding to IgG ・Guaranteed purity: 95% or more purity by SEC ・Activity: IgG binding activity 95% or more ・Not purified by hIgG affinity ・Manufactured according to cGMP
