In the field of biological research, the isolation and purification of specific molecules such as proteins and nucleic acids are crucial to understanding their function and structure. Traditional methods of chromatography, such as ion exchange chromatography, have been the standard in separating these molecules from crude biological samples. However, the process can be time-consuming and require extensive expertise. Magnetic beads, coupled with adsorbent technology, provide a faster and more efficient alternative for fractionating biological molecules.
BcMag™ PEI Magnetic Beads function as powerful Anion Exchange resins. The magnetic beads possess a robust PEI strong anion exchange format, enabling prompt and substantial processing of up to 96 samples in a mere 20-minute span. The technology allows for rapid and efficient fractionation of proteins or nucleic acids from complex biological specimens, such as serum and plasma, either manually or automatically. The refined protein may then be employed in downstream applications, including sample fractionation for 1D and 2D SDS-PAGE, X-ray crystallization, and NMR spectroscopy. Furthermore, strong ion exchangers can prove to be valuable separation tools when weak ion exchangers fall short, owing to the distinct selectivity of weak and strong ion exchangers.
●
Fast and simple – PEI magnetic beads-based format eliminates columns or filters or a laborious repeat of pipetting or centrifugation.
●
Convenient and expandable – PEI magnetic format enables high-throughput processing of multiple samples in parallel with many different automated liquid handling systems.
●
Robust – PEI magnetic beads do not crack or run dry.
●
Low bed volume – Working with small magnetic bead volumes allows for minimal buffer volumes, resulting in concentrated elution fractions.
●
Protein pre-fractionation in cell lysates
●
Optimizing purification conditions for new protein preparation protocols
●
Protein purification and concentration
●
Antibody purification from serum, ascites, or tissue culture supernatant
●
