PurKine™ Antibody Purification Protein A Kit

PurKine™ Protein A Purification system is designed for easy, one-step purification of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. Recombinant protein A is produced in E. coli and functions essentially the same as native Protein A from Staphylococcus aureus. The Protein A molecule contains four high-affinity binding sites capable of interacting with the Fc region from IgG of several species. Protein A is generally preferred for affinity purification of rabbit, Guinea pig, dog and cat IgG. The portfolio allow optimization of process for maximum protein yield, stability and solubility. Tests also confirm that no decrease in performance occurs after at least five repeated uses. The PurKine™ Protein A Purification Resin is also available as prepacked spin column and kit formats.
