Bacteriophage Precipitation and Concentration: Enriches filamentous and tailed phages (e.g., M13, λ, T4) from E. coli lysates using PEG/NaCl-mediated precipitation.

Phage Display Library Processing: Concentrates and purifies M13-derived phage particles during biopanning and amplification workflows.

Viral Vector Concentration: Precipitates and concentrates enveloped and non-enveloped viruses (e.g., lentivirus, retrovirus, AAV) from culture supernatants.

Exosome and EV Isolation: Enriches extracellular vesicles from conditioned media and biofluids via PEG/NaCl precipitation.

Plasmid DNA Precipitation and Cleanup: Concentrates plasmid DNA from dilute solutions and removes salts/contaminants after cloning or ligation.

PCR Product Concentration: Recovers and concentrates DNA amplicons for downstream cloning, sequencing, or labeling.

Macromolecular Crowding/Protein Precipitation: Creates crowding conditions or precipitates protein complexes for preparative workflows.
