Figure 2From: A rapid and robust method for simultaneously measuring changes in the phytohormones ABA, JA and SA in plants following biotic and abiotic stressComparison of absolute yields from freeze dried (FD) or fresh frozen Arabidopsis leaf material. Yields of both JA and SA were consistently higher using fresh frozen material, probably due to a combination of both analyte insolubilisation or volatilisation during the freeze drying process.Back to article page
