Design your FPLC system according to your purification task!
Complete solutions for FPLC (Fast Protein Liquid Chromatography) on a minimum footprint: AZURA® FPLC systems combine flexibility and reliability. The biocompatible/metal free AZURA® FPLC is the perfect choice for your protein purification task.
Design your AZURA Bio purification system to your needs. Multiple functionalities such as automatic sample injection via autosampler, column switching, buffer and sample selection as well as fraction collection enable the user to automate the purification process.
A large range of different detectors make your target molecules visible. Different flow rates and compatibility to columns from all venders offer maximum flexibility. The intuitive software PurityChrom® combines all the advantages of a versatile purification software.
What is Fast Protein Liquid Chromatography (FPLC)?
FPLC is a form of liquid chromatography to purify large biomolecules like proteins or DNA. External factors like high temperature, high pressure, extreme pH, or solvents can disturb the protein structure and are therefore avoided in FPLC. Besides, the method uses column materials out of agarose or polymer material which are very sensitive against pressure fluctuations and air bubbles.

Size Exclusion Chromatography (SEC)
SEC, also referred to as gel permeation chromatography (GPC), separates the components by molecular size while the sample is passing through the stationary phase (one step).
The deciding factor is the pore size distribution of the stationary phase. However, it is not a sieving effect, but a diffusion effect, because large molecules are eluted faster than the small ones.
The smaller molecules can better penetrate into the pores of the stationary phase and thus stay longer in the column than large molecules, which have less space for movement and therefore are more strongly entrained with the eluent. Therefore, the big molecules elute first.
Affinity chromatography is a multi-step process (binding, washing, elution) characterized by specific binding of the target molecules to the column material. Therefore, the ligand of the stationary phase must be matched to the target molecules. In a washing step, all non-specifically bound portions of the sample are removed. The subsequent elution step releases the target molecules.
Ion exchange chromatography separates molecules based on their total charge.
It is a competitive process in which target molecules and all molecules in the sample featuring a polarity of the same direction are first "nonspecifically" bound to the stationary phase and then gradually eluted (2 steps).
For example, a cation exchanger is used for target molecules with a positive overall charge.
The stationary phase itself is of opposite charge, that is negatively charged. Initial binding to the stationary phase occurs under low ionic strength conditions, i.e. the mobile phase with the sample has a low electrolyte content. The elution is achieved by a salt gradient. By increasing the salt concentration, proteins with a weak charge elute first, while at higher salt concentrations proteins with a strong charge elute later.
In protein purification processes different methods are usually combined in a more complex purification strategy. Multi-Method systems can be used to perform all methods used in your purification strategy on one system.
