Binding Assay: For radioligand competition studies, a final concentration of 1x105 THP-1 monocytic leukemia cells are combined with 100 μg of LS WGA PS beads (Amersham, Cat.#: RPNQ 0260) in 40 μL of assay buffer (RPMI 1640 without phenol red, 50 mM HEPES, 5 mM MgCl2, 1 mM CaCl2, 0.1% BSA). The THP-1 cell/bead mixture was added to each well of a 384-well assay plate (PerkinElmer, Cat. #:6007899) containing test compound in 3-fold serial dilution, with final concentrations ranging from 8 μM to 0.14 nM. A final concentration of 0.1 nM [125I]-MIP-1α (PerkinElmer, Cat. #NEX298) in 20 μL assay buffer was added to the reaction. Unlabeled MIP-1α was added in excess to some wells to determine non-specific binding. Sealed assay plates were incubated at room temperature for 12 h then analyzed by LEADseeker.
