Isoamyl Alcohol - Nucleic Acid Purification Applications

1% isoamyl alcohol in phenol:chloroform (25:24:1) reduces foaming and stabilizes the organic phase during genomic DNA isolation.

Molecular labs achieve clear DNA aqueous phase separation preventing protein contamination and chloroform carryover.

Low water solubility maintains organic layer integrity while moderate volatility prevents emulsion formation during vortexing.

Traditional reagent complements column-based kits for large-scale tissue/plant DNA extractions.
