Orexin B, rat, mouse (Rat orexin B) is an endogenous agonist at Orexin receptor with Kis of 420 and 36 nM for OX1 and OX2, respectively. | [Biological Activity]
Orexin B (mouse) is an endogenous agonist of the Orexin receptor with Ki values of 420 and 36 nM for OX1 and OX2, respectively. | [in vivo]
Orexin-B modulates the activity of rod bipolar cells (RBCs) located in the outer retina of rat. Intravitreal injection of orexin-B increased the amplitude of the scotopic electroretinographic b-wave, a reflection of RBC activity, recorded in vivo[4]. | [target]
Ki: 420 nM (OX1), 36 nM (OX2) | [IC 50]
