Antibody Purification
CaptureSelect Antibody Toolbox products are designed to enhance the success of your antibody purification processes. The products offer specific advantages over purification using Proteins A, G, and L, including unique target specificity and simplified elution protocols. Each product has defined target specificity for distinct antibody types and regions, minimizing the need for you to test multiple media products to determine the optimal choice.
CaptureSelect Antibody Toolbox products offer:
- Unique selectivity
- High purity in a single step
- Increased yield
- Flexible formats
- Species specificity
Single-step purification of various antibody formats
A large variety of antibody formats can be purified with one of our Antibody Toolbox products. Unlike the common bacterial coat protein matrices, Proteins A, G, and L, CaptureSelect ligands are developed with defined specificity and high avidity to the target protein of interest. This results in affinity chromatography resins well suited for single-step protein purification.
