TYK2 kinase assay are performed in vitro using Z′-LYTE Kinase Assay Kit-Tyr 3 Peptide (Invitrogen, Cat. No. PV3192). Recombinant human JAK1/2/3 or TYK2 catalytic domains are from Invitrogen (Cat No. PV4774/PV4210/PV3855/PV4790); All reactions (20 μL) are started by adding 2.5 μL of the testing compound in 4% DMSO solution, 5 μL of Kinase/Peptide substrate Mixture (3.2, 0.04, 0.2 or 8 μg/mL for Recombinant human JAK1/2/3 catalytic domains, 4 μM for Z-LYTE Tyr 6 peptide or Z-LYTE Tyr 3 peptide) or Phospho-Peptide solution (Invitrogen, Cat. No. PV3192, diluted with 1.33× Kinase Buffer), 2.5 μL ATP Solution (300/100/40/100 μM, JAK1/JAK2/JAK3/TYK2) or 1.33× Kinase Buffer (Invitrogen, Cat. No. PV3189, 5× diluted with distilled water). The 384-well assay plate (Corning, Cat. No. 3575) is mixed and incubated at room temperature for 1 hour. 5 μL of the Development Solution (Dilute Development Reagent A (Cat. No. PV3297) is diluted to 1/64 with Development Buffer (Cat. No. PV3127) for JAK1, JAK2 and JAK3 assay; Development Reagent A (Cat. No. PV3297) is diluted to 1/2048 with Development Buffer (Cat. No. PV3127) for TYK2 assay. The diluted Development Solution is then added to each well, mixed and incubated at room temperature for another 1 hour. The kinase reaction is then stopped by adding 5 μL of the Stop Reagent (Invitrogen, Cat. No. PV3094), and the plate is read with Wallac 1420 VICTOR3 Multilabel Counter (PerkinElmer) at 445 nm and 520 nm fluorescence. All compounds are initially tested at 8 different concentrations (1 μM down to 0 μM) using a 1:3 serial dilution scheme.
