Figure 5From: A new approach for cytokinin isolation from Arabidopsis tissues using miniaturized purification: pipette tip solid-phase extractionMatrix effects on selectivity and sensitivity of UPLC–ESI(+)-MS/MS method. MRM chromatograms of authentic t/cZR and iPR show the change in signal sensitivity for different A. thaliana extracts, roots (a-c) and shoots (d-f), in minute amounts of plant tissue (1, 2, and 5 mg FW).Back to article page
