Example Data

8 phytohormones can be detected in a single injection. The data below were collected on leaf samples on the UC Riverside campus. Leaves were wounded, or not, for 3 hours. Leaves were then quickly harvested and snap frozen in liquid nitrogen. After freeze drying, leaf material was homogenized to a fine powder, then 10 mg was weighed and phytohormones were extracted then quantified by LC-MS. The method can be applied to various species and sample types (e.g. roots, shoots, and leaves). The number of biological replicates is dependent on experimental conditions, though at least n=4 is recommended.
