| She said it also contained the chemicals isopropanol and t-butanol, meaning it was from industrial origin. |
| The top aqueous phase was pipetted into a fresh tube, and RNA was precipitated with 0.5 ml isopropanol. |
| The organic solvents used in the present study were n-butanol, acetonitrile, methanol, n-propanol, isopropanol, and isobutanol. |
| Total lipid was extracted into chloroform-methanol, dried under a stream of nitrogen and redissolved in isopropanol. |
| They also heard that isopropanol, a chemical used in cleaning products, was found to be in the liquid when it was analysed. |
| However, in Figure 1 and Table 2, the teacher incorrectly wrote that the addition of isopropanol came before the addition of the meat tenderizer. |
