CaptureSelect™ Human Albumin Affinity Matrix

The CaptureSelect™ Human Albumin Affinity Matrix is specifically designed for the purification of human albumin and albumin fusion proteins.

CaptureSelect™ provides a robust and efficient purification process with excellent purity achieved in one step, with high selectivity and yield using the Human Albumin Affinity Matrix.

The gentle elution conditions make the resin suitable for the purification of albumin fusion proteins, especially those that are pH sensitive.

Features of AAV affinity matrix include:

• Highly selective for human albumin
• Unique elution characteristics allowing for gentle elution of albumin fusion proteins
• Excellent scalability
• Non-animal-derived
