    Fisher Scientific lc ms grade ammonium acetate
    Trehalose calibration curves from (a) the enzymatic trehalose assay, (b) the HPLC-RID-based assay, and (c) the <t>LC–MS/MS-based</t> assay. (a) Trehalose calibration curve for the enzymatic trehalose assay is best fit by a linear curve. Standards containing varying concentrations of trehalose (25–1000 μM) were subjected to the enzymatic trehalose assay (sample volume = 20 μL, Trehalose Assay Kit; Megazyme International, Ireland), and the absorbances were measured. Error bars represent the standard deviation ( n = 3). (b) Trehalose calibration curve for the HPLC-RID assay is best fit by a linear curve. Standards containing varying concentrations of trehalose (1–100 mM) were injected onto the HPLC in triplicate (mobile phase = 23:77 water/acetonitrile, injection volume = 50 μL), and the microrefractive index units (μRIU) for trehalose were measured. Error bars represent the standard deviation ( n = 3). (c) Trehalose calibration curve for the LC–MS/MS assay using 13 C 12 -trehalose as an internal standard is best fit by a single polynomial. Standards containing varying concentrations of trehalose (0.1–100 μM) with 5 μM 13 C 12 -trehalose as an internal standard were injected onto the LC–MS/MS in quadruplicate (mobile phase = 20:80 2 mM <t>ammonium</t> <t>acetate</t> in water/2 mM ammonium acetate in acetonitrile, injection volume = 40 μL), and the relative responses for trehalose were calculated. Error bars represent the standard deviation ( n = 4).

    Specificity of assays for trehalose detection. (a) Corrected absorbances for lactose, maltose, sucrose, and trehalose for the enzymatic trehalose assay. All disaccharide concentrations were 1 mM, and the sample volume was 20 μL. For all corrected absorbance values, n = 3. (b) RI chromatogram showing the separation of trehalose (retention time = 33.2 min) from three other disaccharides, sucrose (retention time = 19.3 min), maltose (retention time = 25.5 min), and lactose (retention time = 30.0 min) for the HPLC-RID-based assay. Separation was achieved using a Waters high-performance carbohydrate column (4.6 × 250 mm 2 , 4 μm) held at 35 °C. The mobile phase was composed of 16:84 water/acetonitrile with an isocratic elution over 40 min using a flow rate of 1.4 mL/min. All disaccharide concentrations were 20 mM, and the injection volume was 50 μL. (c) SRM chromatogram showing the separation of trehalose (retention time = 30.3 min) from three other disaccharides, sucrose (retention time = 18.2 min), maltose (retention time = 23.8 min), and lactose (not detected by this method) for the LC–MS/MS-based assay. Separation was achieved using a Waters high-performance carbohydrate column (4.6 × 250 mm 2 , 4 μm) held at 35 °C.
