Purification and Isolation of Cannabinoids: Current Challenges and Perspectives
The current challenges and future perspectives of the purification of cannabinoids from cannabis extracts are presented in this review article.
Separation of Five Steroids on a Hamilton PRP-C18 Reversed-Phase HPLC Column
February 1st 2019In this study, a reversed-phase HPLC method was developed for separation of five steroid hormones with partition coefficients ranging from 1.47 (cortisone) to 4.5 (pregnenolone) on a Hamilton PRP-C18 HPLC column.
Characterization of TSKgel FcR-IIIA-NPR HPLC Column by Top Down Mass Spectrometry
February 1st 2019The purpose of this study is to demonstrate the use of mass spectrometry to characterize the elution profile of a typical IgG1 molecule separation on a TSKgel FcR-IIIA-NPR column, and verify the observations that certain glycan structures impart higher activity to the monoclonal antibody, especially as it relates to the presence of terminal galactose sugars.
