MabSelect PrismA™ X Protein A Resin

Overview

MabSelect PrismA™ X protein A resin is a high-capacity chromatography resin designed to efficiently capture monoclonal antibodies (mAbs). It features exceptional alkaline stability for repeated cleaning in place (CIP) to reduce bioburden.

• Dynamic binding capacity (DBC) higher than 80 g of mAb/L resin at 6 min residence time (RT), saving on resin and buffer consumption.
• Excellent alkaline stability enables efficient cleaning and sanitization using 0.5 to 1.0 M NaOH for improved process economy and robustness.
• Well-established protein A ligand used with several chromatography matrices. Supported by the PrismA ELISA kit for accurate and convenient detection of leached protein A ligand.
• Designed for use in short bed height applications using rapid cycling chromatography (RCC) for improved productivity in the protein A capture step.

DBC at different residence times

The resin is based on a highly cross-linked agarose base matrix with a median particle (bead) size d_50v of 50 μm. The DBC for MabSelect PrismA™ X resin using trastuzumab is excellent. At 6 min, the DBC is 82 mg/mL for MabSelect PrismA™ X resin and 74 mg/mL for MabSelect PrismA™ resin. As the high DBC is realized at short RT, the MabSelect PrismA™ X resin is beneficial for use in RCC to further reduce resin volumes to increase grams of mAb produced per liter of resin and decrease overall resin costs.

Alkaline-stable protein A ligand

We developed the ligand used in MabSelect PrismA™ X and MabSelect PrismA™ resins to withstand high concentrations of NaOH. The enhanced alkaline stability lets you perform efficient cleaning of the resin using 0.5 to 1.0 M NaOH over many purification cycles, providing long resin lifetime and minimized risk for bioburden incidents.

Formats

MabSelect PrismA™ X resin is available as bulk resin in 25 mL, 200 mL, 1 L, 5 L, and 10 L containers. The resin can be ordered in prepacked column formats such as HiTrap™ columns (1 and 5 mL), HiScreen™ columns, and on request as production-scale ReadyToProcess™ columns. These formats enable use from lab-scale to commercial-scale manufacturing.
