What is DEAE Sepharose chromatography?
What is DEAE Sepharose chromatography?
DEAE-Sepharose® is used in affinity chromatography, protein chromatography and ion exchange chromatography. DEAE-Sepharose® has been used to study pathogenesis of human disease and to develop a new assay for detecting the toxins of pathogenic strains of Clostridium difficile.
How does Q Sepharose work?
The charged group of Q-Sepharose is a quarternary amine which carries a non- titratable positive charge. This matrix can be used at alkaline pH values at which the positive charge of the DEAE group would have been titrated. The charged group of S-Sepharose is the sulphonyl group (-SO3¯).
What is SP chromatography?
SP Sepharose Fast Flow is a sulphopropyl (SP) strong cation exchange chromatography resin for fast protein purification. Well established strong cation exchanger. Based on Sepharose Fast Flow ion exchange resin. High chemical stability enables proven CIP and sanitization protocols.
What are cationic exchangers?
Definition of cation exchanger : a cation-exchange agent that can exchange its cation with the cation or cations of a solution passed through it and that consists of an insoluble saltlike or acidic substance:as. a : a natural or synthetic zeolite.
What is DEAE Sepharose Fast Flow?
DEAE Sepharose Fast Flow is a weak anion exchanger based on the well established Sepharose® Fast Flow ion exchange platform, extensively used for preparative protein separations in both research and industrial applications.
What is DEAE cellulose used for?
Diethylaminoethyl cellulose (DEAE-C) is a positively charged resin used in ion-exchange chromatography, a type of column chromatography, for the separation and purification of proteins and nucleic acids.
How do you clean Q Sepharose?
you can easily clean Q sepharose resin with 4-5 culun volume of 2M NaCl then followed by 8M Urea or 7M guanidium hydrochloride and excess for distilled water and try to store your resin with at least 20% ethanol for long term storage. You can never fully clean Q sepharose.
What is cation exchange resin used for?
Cation-exchange resins are used to treat hyperkalaemia by accelerating potassium loss through the gut, especially in the context of poor urine output or before dialysis (the most effective means of treating hyperkalaemia).
What is Cex chromatography?
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.
What type of chromatography is HPLC?
High Performance Liquid Chromatography (HPLC) is a form of column chromatography that pumps a sample mixture or analyte in a solvent (known as the mobile phase) at high pressure through a column with chromatographic packing material (stationary phase).
What are cationic and anionic exchangers?
Ion exchangers are either cation exchangers, which exchange positively charged ions (cations), or anion exchangers, which exchange negatively charged ions (anions). There are also amphoteric exchangers that are able to exchange both cations and anions simultaneously.
