CaptureSelect™ Human Albumin Affinity Matrix has been specifically designed for the purification of human albumin and albumin fusion proteins.
Features of this affinity matrix include:
• Highly selective for human albumin • Unique elution characteristics allowing for gentle elution of albumin fusion proteins • Excellent scalability • Non-animal-derived
The high selectivity and yields obtained using CaptureSelect™ Human Albumin Affinity Matrix enable a robust and efficient purification process with excellent purity obtained in one step. The mild elution conditions make the resin suitable for the purification of albumin fusion proteins, especially those that are pH sensitive.
Free of Animal Components Our CaptureSelect™ products are affinity ligands created by a proprietary technology based on Camelid-derived single domain antibody fragments. The ligand is a 13 kDa single domain fragment comprising the 3 CDRs that form the antigen binding domain, efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
