FERb 033 (0-100 μM) shows specificity on full-length of estrogen receptor (ESR) in transactivation[2].
FERb 033 (10 nM, 2 h) treatment mildly decreases Ca2+ response in airway smooth muscle (ASM) cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
