Capto MMC is a multimodal cation exchanger with the properties of a weak cation exchanger. In addition to electrostatic interactions, the ligand structure provides for additional interaction modes such as hydrophobic interaction, hydrogen bonding, and thiophilic interaction.
Desalting at laboratory scale is a well-proven, simple, and fast method that will rapidly remove low molecular weight contaminants at the same time as transferring the sample into the desired buffer in a single step.
This page shows how to separate proteins and peptides with afﬁnity for metal ions by immobilized metal chelate afﬁnity chromatography using HiTrap Chelating HP, Chelating Sepharose Fast Flow,His MicroSpin Purification Module or HisTrap Kit from Cytiva.
Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties
Bioanalysis for large molecules, like Proteins or specific Biotherapeutics, refer to a set of methods, assays, and procedures that enable scientists to analyze specific proteins found in living organisms and the biochemical reactions underlying life processes.
Flash-Chromatography columns are available with ball joints or threaded standard taper joints and EZSafe™ connections and are useful for rapid, preparative separations. Large columns are also available with Ace-Thred connectors.
Pressure is generated by the flow through the chromatographic system. For optimal chromatography functionality, it is important to understand the principle of the pressure drop over the different parts of a system.
Poor-quality eluent components can cause a phenomenon referred to as “ghosting”. Trace levels of organic impurities bind to the medium, concentrating during equilibration and sample application. When elution begins, these contaminants appear in the chromatogram as unknown, or “ghost” peaks.
Thiol-containing substances can be isolated selectively by covalent binding to an activated thiolated matrix via thiol-disulphide exchange to form a mixed disulphide bond. After washing away unbound material, the thiol-containing substance is eluted by reducing the disulphide bond. This technique
