Reliable chromatographic assay for measuring of indoleamine 2,3-dioxygenase 1 (IDO1) activity in human cancer cells

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2021
The kynurenine pathway is the major tryptophan degradation routes generating bioactive compounds important in physiology and diseases. Depending on cell type it is initiated enzymatically by tryptophan-2,3-dioxygenase (TDO) or indoleamine-2,3-dioxygenase

Browning's Spectroscope [PDF]

open access: yesNature, 1870
IN the last number of NATURE there is a description by Prof. Young of a spectroscope, in which the prisms are made to alter their positions relatively to each other by bending backwards and forwards the metal work to which they are attached. I should of course not wish to offer any opinion on the efficiency or otherwise of this arrangement.
