General description

Compounds are arranged in 96-well format in 16 racks of 80, one compound per well (250 μl at 10 mM in DMSO).


LOPAC®1280 has been used:
  • in the screening of novel inhibitors for chemotaxis/ migration using Dictyostelium as a model
  • to test the ability to modulate and to measure forskolin-stimulated cAMP levels in CHO-hCB2 cells and to modulate ligand-induced receptor/β-arrestin interaction
  • in screening of small molecules for activating bone morphogenetic protein (BMP) signaling
  • in screening of compounds that plays a role in regulating subcellular localization of nitric oxide associated protein 1 (NOA1) protein
