15-LOX-1/Polyunsaturated fatty acid lipoxygenase ALOX15 in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL2903] [GtoPdb: 1388] [UniProtKB: P16050]
ChEMBL	Lipoxygenase-15 Assay: Briefly, reactions were carried out in Corning 96 half-well black, flat bottom assay plates and contained final concentrations of 50 μM arachidonic acid (Cayman Chemical) as a substrate, 1:10 (v:v) cholate mix (2% (w:v) sodium cholate (Sigma-Aldrich) and 2% (v:v) DMSO with or without test compounds), 40 μM dihydrorhodamine 123 (Sigma-Aldrich) and 1:200 lipoxygenase-15 enzyme (soybean enzyme from Lipoxygenase Inhibitor Screening Assay Kit Item No. 760700 (Cayman Chemical)) in 100 mM Tris-HCl, pH 7.5. Cholate mix contained 2% (w:v) sodium cholate dissolved in 2% (v:v) DMSO. Cholate mix is used for the positive control wells (100% enzymatic activity). Due to the fact, that test compound stocks were dissolved in 100% DMSO, cholate mix was adjusted (sodium cholate was dissolved in water) and test compound DMSO stocks were further diluted with this solution in order to keep the final DMSO concentration in reaction below 0.2% and equal in all wells. Assay buffers and DMSO were deoxygenated to keep test compounds in the reduced state**. Stock solutions of test compounds were prepared in DMSO and then diluted to final assay concentrations in cholate mix such that final cholate and DMSO concentrations were maintained at 0.2%. Reactions were initiated by the addition of 50 μL of enzyme mix (80 μM dihydrorhodamine 123 and 1:100 lipoxygenase-15 enzyme in 100 mM Tris-HCl, pH 7.5) to wells containing 50 μL substrate and cholate mix in 100 mM Tris-HCl, pH 7.5 and linear rates were assessed by measuring fluorescence, using excitation/emission of 485/535 nm on a Hidex Sense microplate reader every 10 seconds for 5 minutes at room temperature.
