CaptureSelect FcXP Affinity Matrix can be used for the purification of IgG and Fc fusion proteins directly from complex source materials and enables a robust and efficient purification process with excellent purity obtained in one step.

Features of this affinity matrix include:
• Mild elution, making it suitable for Fc fusion proteins
• Human-specific, no binding to bovine antibodies
• Excellent scalability
• Non-animal derived

Capture Select Antibody Selectivity - Next Generation FC Binder

CaptureSelect™ Technology: Antibody Selectivity and Affinity

Dynamic Binding Capacity at 10% Breakthrough

Capacities were measured with monoclonal Rituximab (titer: 5 g/l) and Polyclonal IgG (titer: 7 g/l) in 4 ml columns (0.5 x 20 cm).
Bound protein eluted using 20 mM Citric Acid pH 4.0
 

Elution Conditions

Elution efficiency with monoclonal antibody feed (Rituximab, titer 1.7 g/l) at 8 min residence time.
Bound mAb, 20 mM
Washed using Acetic Acid pH 4.0 and simplified with 100 mM Glycine pH 2.0.
(CaptureSelect FcXP affinity resin shows efficient elution at mild pH (>95% at pH4.0).)
