Procedures for BTK OMNIA Assay
|
The Omnia continuous read assay is performed essentially as described by the vendor. The assay conditions are: 40 μM ATP (1X KMATP), 10 μM Y5-Sox, and 10 nM BTK enzyme. Briefly, a substrate mix containing 1.13X ATP and the Y5 Sox substrate is first prepared in 1X Omnia Kinase Reaction Buffer (KRB) consisting of 20 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EGTA, 5 mMβ-glycerophosphate, 5% glycerol, and 0.2 mM DTT. For IC50 measurements, 5 μL of enzyme are incubated with serially diluted (3-fold) compounds prepared in 50% DMSO in a Corning (#3574) 384-well, white, non-binding surface microtiter plate at 25°C for 30 min. Kinase reactions are started with the addition of 45 μL of the ATP/Y5 substrate mix and monitored at λex360/λem485 in a Synergy 4 plate reader for 60 minutes. Progress curves from each well are examined for linear reaction kinetics and fit statistics. Initial velocity from each reaction is determined from the slope of a plot of relative fluorescence units versus time and then plotted against inhibitor concentration to estimate IC50 using the Response, Variable Slope model in GraphPad Prism from GraphPad Software.

A suspension of resting purified naïve human B cells isolated by negative selection in RPMI is prepared at 0.4–0.5 × 106 cells/ml. Cells are mixed together with α-human IgM (final concentration of 5 μg/ml in each well) and vehicle (dimethyl sulfoxide) or AVL-292 (final concentrations of 0.01, 0.1, 1.0, 10.0, 100.0, or 1000 nM per well) and seeded in a 96-well plate. Cells are incubated for 56 hours in a humidified incubator maintained at 37°C and 5% CO2. 3H-Thymidine is added (final concentration of 1 μCi in each well) and cells are incubated overnight, harvested, and measured for 3H incorporation. Experiments are performed in triplicate.

Например, чтобы изменить дозу ресвератрола, используемую для мыши (22,4 мг / кг), на дозу, основанную на BSA для крысы, умножьте 22,4 мг / кг на коэффициент Km для мыши, а затем разделите на коэффициент Km для крыса. Этот расчет дает эквивалентную дозу ресвератрола для крыс 11,2 мг / кг.
