CaptureSelect™ ligands and affinity chromatography resins can be used for the highly efficient capturing step for a variety of Biopharmaceuticals.


  • 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.
