Plasmid purification is a technique used to isolate and purify plasmid DNA from genomic DNA, proteins, ribosomes, and the bacterial cell wall. A plasmid is a small, circular, double-stranded DNA that is used as a carrier of specific DNA molecules. When introduced into a host organism via transformation, a plasmid will be replicated, creating numerous copies of the DNA fragment under study. In this video, a step-by-step generalized procedure is described for how to perform plasmid purification.

Gel Purification

Gel purification is used to recover DNA fragments after electrophoretic separation. DNA recovery from an agarose gel includes three basic steps: binding, washing and eluting from a silica column. DNA is believed to bind to silica in the presence of high salt via a salt bridge. Following binding, DNA is washed of impurities and eluted under low salt conditions disrupting this interaction. This video goes through a step-by-step, generalized procedure for cutting out a band from the gel, gel...

Peptide adsorption to plasticware during traditional tip-based serial dilutions can significantly impact potency determination and confound the understanding of structure-activity relationships used for lead identification and lead optimization phases of drug discovery. Here methods for automated acoustic non-contact serial dilution of peptide samples are described.
FAQs
Magnetic beads provide a capture surface for molecules targeted during purification. After the sample is combined with purification reagents, programmed handling supports contact between the sample and capture medium. Washing removes contaminants, while elution releases purified material for downstream use. This sequence links physical separation with reagent processing and helps standardize recovery across repeated samples.
Programmed liquid handling controls the transfer and combination of samples and purification reagents, while timed processing keeps workflow steps in a defined sequence. Standardization reduces dependence on manual timing and pipetting, which can limit handling variation. In biology workflows, this supports more consistent preparation across larger sample sets.
Washing and elution serve different purification purposes. Washing removes contaminants that remain after target capture, whereas elution releases the purified material from the capture or separation medium. Keeping these stages distinct is important because the first improves cleanliness and the second makes the isolated material available for sequencing, diagnostics, genotyping, or biochemical analysis.
The same general workflow can prepare nucleic acids, proteins, and other biomolecules, although the sample and purification reagents determine what target is isolated. This flexibility allows one platform to support varied biological workflows rather than a single assay type. Resulting material can then enter sequencing, molecular diagnostics, genotyping, or downstream biochemical analysis.
A typical run begins with sample and reagent loading, followed by programmed combination and timed processing. The system then enables target capture on magnetic beads or another separation medium, performs washing to remove contaminants, and carries out elution. The purified output is collected for a downstream application. This ordered workflow minimizes repetitive manual intervention while keeping major purification stages consistent.
Key components include the biological sample, purification reagents, a capture medium such as magnetic beads or other separation media, and the platform’s programmed liquid-handling system. Timing controls when processing steps occur, and washing and elution stages determine how contaminants are removed and purified material is released. These elements work together as a standardized preparation workflow.
Laboratories can use an Automated Purification System when they need reproducible preparation across many biological specimens or want to reduce repetitive manual handling. The approach is relevant to sequencing, molecular diagnostics, genotyping, and downstream biochemical analysis, where purified nucleic acids, proteins, or other biomolecules serve as inputs. Its value is greatest when consistency and throughput matter.
By standardizing purification steps, the platform can reduce handling errors, conserve sample, and improve workflow efficiency. These effects matter in biology because laboratories often need material prepared consistently for different downstream analyses. The system’s output is not itself the final biological result; rather, it provides purified material that supports subsequent sequencing, diagnostics, genotyping, or biochemical investigation.
