Evaluation of monoclonal antibody and phenolic extraction from transgenic Lemna for purification process development.

13 Oct 2009 Several pharmaceutical protein products made in transgenic plant hosts are advancing through clinical trials. Plant hosts present a different set of impurities from which the proteins must be purified compared to other expression hosts such as ... Read more...

Assigning glucose or galactose as the primary glycosidic sugar in 3-O-mono-, di- and triglycosides of kaempferol using negative ion electrospray and serial mass spectrometry.

29 Sep 2009 Kaempferol 3-O-beta-glucopyranoside, kaempferol 3-O-beta-galactopyranoside and higher glycosides of these two flavonoids with alpha-rhamnose at C-2 and/or C-6 of the primary sugar were studied by negative ion electrospray ionisation and serial mass ... Read more...

A rapid screening method for prenylated flavonoids with ultra-high-performance liquid chromatography/electrospray ionisation mass spectrometry in licorice root extracts.

29 Sep 2009 Due to their substitution with an isoprenoid group, prenylated flavonoids have an increased affinity for biological membranes and target proteins, enhancing their potential bioactivity. Although many prenylated flavonoids have been described, there ... Read more...
