Heparin Removed with Chitosan Microspheres
Researchers from Jagiellonian University (Krakow, Poland) used pH-sensitive chitosan microspheres that had been cross-linked with genipin ? an aglycone derived from a compound present in gardenia fruit extract ? to bind heparin at pH levels comparable to that found in blood.
Researchers from Jagiellonian University (Krakow, Poland) used pH-sensitive chitosan microspheres that had been cross-linked with genipin — an aglycone derived from a compound present in gardenia fruit extract — to bind heparin at pH levels comparable to that found in blood. The binding was found to be pH dependent and was faster at lower pH. The chitosan microspheres swell at pH values below 6.5 and shrink somewhat at pH values greater than 6.5.
Exploring Nitrogen Exudation in Cotton with HPLC and FT-ICR-MS
December 5th 2024Researchers used high performance liquid chromatography and untargeted metabolomics by Fourier-transform ion cyclotron resonance-mass spectrometry to highlight the critical role of root exudates in drought tolerance.
Inside the Laboratory: Using GC–MS to Analyze Bio-Oil Compositions in the Goldfarb Group
December 5th 2024In this edition of “Inside the Laboratory,” Jillian Goldfarb of Cornell University discusses her laboratory’s work with using gas chromatography–mass spectrometry (GC–MS) to characterize compounds present in biofuels.
