How do you remove silica from column chromatography?
Fine particle of silica can be tentatively eliminated by passing the product + small quantity of solvent into a pasteur pipette containing at the bottom a small plug of silanized glasswool. If the solvent volume is important , use several pipettes. Thank all of you very much.
What are the two types of ion exchange chromatography?
The two types of ion chromatography are anion-exchange and cation-exchange. Cation-exchange chromatography is used when the molecule of interest is positively charged.
What is resin column?
Resin Column / Cation Column An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. The cation resin replaces contaminating cations such as Ca++, Mg++, Na+, NH4+, and amines in the sample with hydrogen ions.
Why resin is used in ion exchange chromatography?
Water purification In this application, ion-exchange resins are used to remove poisonous (e.g. copper) and hazardous metal (e.g. lead or cadmium) ions from solution, replacing them with more innocuous ions, such as sodium and potassium.
What is the difference between Agarose and Sepharose?
The answer is simple. It really doesn't matter as they are in fact the same. Sepharose is a tradename for a crosslinked, beaded-form of a polysaccharide polymer material extracted from seaweed. Its brand name is derived from Separation-Pharmacia-Agarose.
Why are Sepharose resins commonly used for protein purification?
The reliability and well-documented performance of the resins have made them a common choice for capture and intermediate purification of proteins in both research and industry.
How does HIC work?
HIC utilizes a reversible interaction between the proteins and the hydrophobic ligand of a HIC resin. The interaction between hydrophobic proteins and a HIC resin is greatly influenced by the running buffer. A high salt concentration enhances the interaction. Lowering the salt concentration weakens the interaction.
How does cation exchange chromatography work?
Cation exchange chromatography is a form of ion exchange chromatography (IEX), which is used to separate molecules based on their net surface charge. Cation exchange chromatography, more specifically, uses a negatively charged ion exchange resin with an affinity for molecules having net positive surface charges.
