How to use
In Vitro:
Galanin Receptor Ligand M35 TFA has a dual effect on the galanin mediated inhibition of Forskolin stimulated cyclic AMP production in Rin m 5F cells. Co-applied with galanin (10 nM), Galanin Receptor Ligand M35 TFA at low concentrations (1 nM) is able to reverse the inhibitory effect of galanin. But when present at higher concentrations (15 and 30 nM), Galanin Receptor Ligand M35 TFA acts as a galanin receptor agonist, inhibiting the forskolin stimulated production of cAMP.
In Vivo:
Galanin Receptor Ligand M35 TFA (6 nM/10 μL; i.c.v.) improves the ability of the male Sprague-Dnwley rats to acquire the swim maze task.
