Thermo Scientific™ POROS™ CaptureSelect™ hCG Affinity HPLC Columns
Tous les produits Thermo Scientific ProduitsDescription
POROS CaptureSelect hCG Affinity HPLC columns incorporate the advantages of high-speed POROS chromatography resins with the unique selectivity of CaptureSelect affinity ligands. CaptureSelect hCG Affinity HPLC columns recognize the alpha chain of human chorionic gonadotropin (hCG), enabling quantitation and small scale purification of hCG from the (recombinant) source material. Because it recognizes the alpha chain, it also binds LH, FSH, and TSH.
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.
Features of POROS CaptureSelect hCG Affinity HPLC columns include:
- Fast—POROS resins enable quantitation or purification of products in minutes
- Hands-off operation—HPLC method can be automated for a streamlined operation
- Robust—designed to deliver high-performance purification over hundreds of chromatography cycles
High speed with high specificity
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 HPLC columns are for use with HPLC systems, which allows the automation of chromatography methods, data collection, and data analysis. In addition, the immobilized affinity ligand enables 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 regimen results in strong re-use performance. POROS Affinity HPLC columns can be cycled hundreds of times for cost-effective and reproducible quantitation or purification.
