CaptureSelect™ ligands and affinity chromatography resins can be used for the highly efficient capturing step for a variety of biopharmaceuticals.
Affinity resins
  • Selectivity
    high purity in single step/feed-stock independent

  • Mild elution conditions
    retaining biological activity of target

  • Reduction of process steps
    higher yields, reduced costs

  • Efficient clearance of HCP, DNA, virus
    high selectivity in capture step

We offer products for large-scale purification of various biologics such as antibodies and antibody fragments, fusion proteins, and hormones.

We also offer complementery leakage ELISA ›.
