Analytical groups supporting biologic drug development require rapid, sensitive, and precise methods for protein quantitation from cell culture, fermentation harvests, or purification intermediates. It is critical for biopharmaceutical manufacturers to be able to monitor bioreactor product titers to determine when to harvest or abort a reactor cycle.

Poros™ CaptureSelect™ LC Lambda HPLC columns incorporate the advantages of high-speed Poros™ chromatography resins with the unique selectivity of CaptureSelect™ ligands. The combination allows three minute quantitation of Fabs, immunoglobulins, and bispecific antibodies having a Lambda light chain.

Features:

• Broad utility—POROS™ A, G and CaptureSelect™affinity ligands address most biological drug classes
• Rapid—POROS™ resins offer fast quantitation or purification of immunoglobulins and fusion proteins
• Hands-off operation—HPLC method can be automated for streamlined operation
• Robust—deliver high-performance purification over hundreds of chromatography cycles

High Speed with High Specificity

The combination of CaptureSelect™ LC Lambda affinity ligands when combined with POROS™ 20 μm resin provides a high flow rate, high performance chromatography solution for the rapid quantitation and small-scale purification of all immunoglobulins and Fabs having a Lambda light chain (all subclasses).

POROS™ high performance chromatography allows for the quantitation of product from clarified harvest or partially purified intermediates—typically in under three minutes. Moreover, only minimal sample preparation (0.2 μm filtration) is required, and the eluted product is highly purified and suitable for further analysis including mass spectrometry.

Automation

POROS™ affinity chromatography columns are suitable for use with HPLC systems, which allows the automation of chromatography methods, data collection, and data analysis. In addition, the immobilized affinity ligands enable one method and buffer system to be used across a class of molecules, streamlining analytical approaches.

Multiple Cycles

Proper sample preparation, adherence to column operating instructions, and the use of an optimized column cleaning regime results in strong re-use performance. POROS™ Affinity Chromatography columns can be cycled hundreds of times for cost-effective and reproducible quantitation or purification.
