Here, we describe a protocol for the purification of highly active Hsp104, a hexameric AAA+ protein from yeast, which couples ATP hydrolysis to protein disaggregation. This scheme exploits a His6-tagged construct for affinity purification from E. coli followed by anion-exchange chromatography, His6-tag removal with TEV protease, and size-exclusion chromatography.

This video demonstrates a technique for purifying monoclonal antibodies from the culture supernatant obtained from an antibody-producing cell culture. The process involves using a matrix of crosslinked agarose beads with conjugated Protein A, which immobilizes the antibodies in the supernatant on the beads, allowing for effective separation from contaminants. By applying an elution buffer with low pH, the protein A-antibody interaction is loosened, facilitating the collection of...

FAQs
The separation mode should match the property that distinguishes the target from other sample components. Affinity chromatography uses differences in binding, ion-exchange chromatography separates according to charge, and size-exclusion chromatography separates according to molecular size. Selecting among these modes allows a bioengineer to tailor the purification strategy to the biomolecule and the composition of the starting sample.
Elution depends on how strongly each sample component interacts with the selected stationary phase. Components with different affinity, charge, or molecular size move through the column differently and therefore appear at different points in the run. The detector records signals such as ultraviolet absorbance, helping identify when separated material exits and which fractions may contain the target.
Buffered conditions help maintain an environment that preserves biological activity while the sample passes through the column. This consideration is especially important when the purified biomolecule will support biochemical, structural, or therapeutic research. Automated pumping and signal monitoring further provide a consistent workflow for tracking separation without relying only on manual handling of the sample.
A typical workflow places the sample in a system where a pump moves it through a column containing the selected stationary phase. As components separate, detectors monitor signals such as ultraviolet absorbance. The system collects the emerging material in separate fractions, which can then be examined individually or combined when they contain the desired purified biomolecule.
Collected fractions provide discrete portions of the column output for downstream evaluation. Researchers can analyze their detector signals or other available measurements to determine which portions contain the desired material, then pool compatible fractions. This approach converts the continuous separation process into selected sample portions suitable for later biochemical, structural, or therapeutic research.
Bioengineers use this approach when they need defined biomolecules for further investigation or processing. Supported applications include purifying recombinant proteins, processing antibodies, and preparing materials for structural and biochemical studies. The same capability also contributes to therapeutic research, where preserving biological activity during purification can be important for evaluating the resulting biomolecule.
