Analytical teams that support biologic drug development require rapid, sensitive, and precise methods for protein quantitation from cell culture, fermentations broths, 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™ FSH HPLC columns incorporate the advantages of high-speed POROS™ chromatography resins with the unique selectivity of CaptureSelect™ ligands, enabling 3-minute quantitation of human follicle stimulating hormone (FSH).
Features of this class of chromotography columns:
• 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—delivers high-performance purification over hundreds of chromatography cycles
High Speed with High Specificity
The combination of CaptureSelect™ FSH affinity ligand with POROS™ 20 µm resin provides a high flow-rate, high performance chromatography solution for the rapid quantitation and small-scale purification of FSH.
POROS™ high performance chromatography allows for the quantitation of product from clarified harvest or partially purified intermediates—typically in less than 3 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.
POROS™ affinity chromatography columns are suitable for use with HPLC systems, allowing for the automation of chromatography, 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.
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.
