Teap buffer
WebbGenerally, TEAP 2.3 is used as the initial purification, with consequent TEAP runs of increasing pH as needed (up to pH = 7.0 for column stability). When an appropriate level of purity has been achieved, the phosphate salt is removed by diluting with H 2 O (2–3×) and reloading the pure material.

Webb23 mars 2012 · The second mobile phase system evaluated was based on the use of a pH 3.0 TEAP buffer for both maintaining an acidic pH and for elution of the proteins from the column by using a gradient of increasing TEAP buffer content (5–300 mM). Again, an acidic pH was selected to insure that all the kafirin proteins were positively charged. Webb7 aug. 2008 · The best separation was obtained with TEAP buffer (pH 4.0; 50 mM)–MeCN (50:50, v/v). The spots were yellow colored; the h R F values for resolved diastereomers are given in Table 1 . It was observed that h R F values increased with increasing acetonitrile concentration (up to 65%) in mobile phase, while the S / R ratio of h R F values decreased.
