How do ion-exchange chromatography, gel filtration, and affinity chromatography differ from each other? Describe the general steps of affinity chromatography, describing what is accomplished in each step. Explain the differences between normal and reversed-phase chromatography. Name and briefly explain two...
Soluble LPMO products were analyzed and quantified by high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) using a Dionex ICS 5000 system (Thermo Scientific, Sunnyvale, CA, USA) equipped with a CarboPac PA200 analytical column (3 × 250 mm) and a gua...
(DA)-PhyC-SpyCatcher and PhyC samples used for CD were dialyzed 3 times into 10 mM Tris-HCl pH 8.0 with 2A mniMonC-eaxCclh2aanngde then purified again using anion-exchange chromatography was performed using a to polish the samples and remove 1 mL HiTrap HP Q column (GE ...

Which of the following chromatography technique can be applied for desalting of proteins? As mentioned above,gel filtrationcan be effectively utilized for protein desalting and is accomplished by first equilibrating the gel filtration column with water. However, buffer exchange is accomplished by first ...
In Ion exchange chromatography, what determines whether or not or how strongly an analyte adsorbs to the stationary phase? Briefly describe the conditions you will observe when you reach the end point of the back-titration. Explain how sulfate ion (as an example of an...

ERLIC Chromatography The tryptic digest of the protein mixture isolated by Jacalin affinity-chromatography was fractionated on a weak anion-exchange column (PolyWAX LP, PolyLC Inc, 4.6 mm ID × 20 cm, 5 μm particle size, 300A pore size) applying the following gradient program (flow rate: 1...
Alternatively, chromatographic methods may be classified based on the nature of the interaction between the stationary phase and the substances being separated. For example, in ion-exchange chromatography, the dominant force that retards solutes is ionic in nature. ...
Convective Interaction Media (CIM) monolithic materials with anion-exchanging capabilities have been particularly successful in tobamovirus studies (Table 1). Though chromatography is probably one of the most important purification methods for bioproduction, it is still not commonly applied in routine labs...
