Affinity Resins—Biosimilars and Recombinant Proteins
We have developed a unique portfolio of affinity resins to help you develop biosimilars, biobetters, and other types of recombinant proteins. These affinity resins can be used for clinical and commercial production.
CaptureSelect Affinity resin benefits:
- High Selectivity─high purity in a single capture step, independent of feedstock
- Mild elution conditions─retention of biological activity of target
- Reduction of process steps─helps reduce costs, allows higher yields
- Efficient clearance of impurities
In addition to affinity resins, we also offer product-specific ELISAs to measure any ligand potentially leaching from the column.
The graphic below depicts a typical workflow in which CaptureSelect resin can be used for a primary capture step for the efficient production of recombinant proteins.
CaptureSelect affinity matrices:
| Product | Target applications | Uniqueness | RoboColumn™ format |
|---|---|---|---|
| CaptureSelect Follicle Stimulating Hormone (FSH) | Human follicle stimulating hormone | Binds only intact FSH due to alpha/beta chain epitope | |
| CaptureSelect Human Albumin | Human serum albumin, albumin fusion proteins | Mild elution conditions help to protect fusion partner | X |
| CaptureSelect hCG | Binds to the alpha chain of hCG (human chorionic gonadotropin) | Selective for hCG, with cross-binding to LH, FSH, and TSH | |
| CaptureSelect hGH | Binds recombinant human Growth Hormone | High yield and retained activity | |
| CaptureSelect Factor X | Human Factor X from plasma and recombinant sources | Binds both Factor X and Factor Xa in the presence of calcium, offering mild elution at neutral pH using EDTA | |
| CaptureSelect tPA | Human tissue plasminogen activator (tPA) | The only tPA affinity resin available on the market | |
| CaptureSelect TSH | Human Thyroid Stimulating Hormone | Selective for TSH with no cross binding to hormones of the Gonadotropin family | |
| CaptureSelect C-tagXL | Binds the short C-tag sequence E-P-E-A (glutamic acid - proline - glutamic acid – alanine) when this affinity tag is fused at the C-terminus of a target protein | Optimized to obtain high yields in protein purification |
Quantitate the yield of your proteins during the production process with our analytical columns or develop your own analytical assay with CaptureSelect Ligand Conjugates.
When your specific process needs cannot be met with current products, our custom chromatography services are available to build you a unique solution. For more information, please visit Custom Capabilities .
