mL sealed vial (Scheme 1). After being stirred in the dark at room temperature for 24 h, the reaction mixture was purified with a semi-preparative HPLC column using a 28%-55% gradient elution system with aq. NH4OAc buffer (10 mM, pH 7.0) (solvent A) and MeCN (solvent B) over 20 min at 2.0 mL/min. The final product AP2H-

Thermo Scientific™ 11mm Plastic Crimp/Snap Top Vials provide an economical alternative to glass for some applications. Polypropylene is chemically inert and suitable for most chromatography applications, and can be used when levels of inorganic ions have to be kept to an absolute minimum. Type: Screw Thread Vial Vial Closure Size: 10-425mm

Sep 01, 2004 · A modified high-performance liquid chromatography (HPLC) method, based on Davidson and Sadowski [Meth. Enzymol. 282 (1997) 408], with fluorescence detection after zinc postcolumn reduction was developed and validated for the analysis of phylloquinone (vitamin K 1) in plasma or serum samples.Compensation for procedural losses of vitamin K 1 was made by the method of internal

of five different positions for reagent vials (Reagent Vial A to D and an additional PrepVial position). The PrepVial may also be used as a target vial for mixing sample and reagent. This procedure is called in-vial mixing. The fastest and most sample-saving method of reagent mixing is the in-needle mixing procedure. It is performed directly

Jan 19, 2016 · Reconstitute a 60 nmol vial of horse apomyoglobin in 6 ml of 10 mM ammonium bicarbonate (NH 4 HCO 3). The ammonium bicarbonate is not adjusted for pH. Tris base, pH 8, can be substituted for ammonium bicarbonate in this step. Add 20ugs of Promega modified trypsin, and let sit on the bench top, or in a drawer at ambient temperature.
