ReadyToProcess Capto Core 700 columns 1 L and larger columns for clinical. Capto Core 700 is a core-shell chromatographic support with an adsorbing core contained within an inert shell layer designed to purify larger biomolecules and bioparticles in a flow-through mode. The combination of this downstream strategy following production in E. The 3 steps purification protocol uses a recently developed multimodal size-exclusion chromatography medium (Capto™ Core 700) in combination with detergent extraction and size-exclusion polishing to reach a 89% VLP purity with a 19% yield. Recombinant VLPs derived from the RNA bacteriophage MS2 displaying an epitope from the ectodomain of Matrix 2 protein from influenza A virus were produced and purified. Shop Cytiva Capto Core 700 at Fishersci.pt. In the present study we set up a size-exclusion chromatography-based, scalable purification protocol for the purification of a VLP-based influenza A vaccine produced in Escherichia coli. Capto Core 700 is designed for intermediate purification and polishing of viruses and other large biomolecules. In particular, a rapid low cost purification process has been identified as a remaining key challenge in manufacturing process development. In recent years, the development of genetically engineered recombinant VLPs has accelerated the need for new, improved downstream processes. This chromatography resin has both size exclusion and binding properties. 28-9958-80 AC 7 Sample load Capto Core 700 works as a scavenger, meaning that the target will pass in the flow-through fraction while the impurities bind to the interior of the beads. ![]() The size separating mode of operation could be compared to gel filtration (size exclusion chromatography), which is a common Fig 1. ![]() Several VLP-based vaccines are currently licensed and commercialized, and many vaccine candidates are now under preclinical and clinical studies. Capto Core 700, 25 mL Novel core bead technology and multimodal, octylamine ligand give Capto Core 700 dual functionality. The Benzonase endonuclease itself can also be removed by Capto Core 700. Capto Core 700 is built on the core bead technology which allows for dual functionality combining size separation with binding chromatography. Size, oligomer assembly and repetitiveness of epitopes are optimal features to induce strong immune responses. Virus-like particles (VLPs) are promising molecular structures for the design and construction of novel vaccines, diagnostic tools, and gene therapy vectors.
