Numerous attempts to prepare glacial acetic acid by distillation of vinegar proved to be in vain‚ however. Lavoisier believed he could distinguish acetic acid from acetous acid‚ the hypothetical acid of vinegar‚ which he thought was

    Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase
