Easy to use, goes into solution well.
By Corinne Kiessling on 01/04/2018
Assay Type: In Vivo
Species: Rat

Used this for validation of a molecular target during behavioral testing in rats. This was used to selectively block central 5-HT1A receptors. Dissolved in water at a dose of 0.5 mg/ ml and 1.0 mg/ml and injected subcutaneously in rats. Injections were followed by behavioral testing.
