Analysis of Histamine by On-Column Derivertization

Histamine was analyzed by on-column derivertization using Asahipak ODP-50 4E. When a stimulation, enough to cause inflammation, is applied to mast cells, they release histamine and other physiologically active substances as a result of their cell degradation. The analysis of histamine is widely performed using mast cells by bioassay to assess their inflammation and/or allergy.
This chromatograms show analysis of histamine released during the degradation induced by the compounds 48/80(A), mastobaran (B) and somatostatin (C). Histamine analysis is possible without the interference of coexisting substances.
