In Vitro

Muscarine (100 µM) induces an intracellular calcium signal amplitude similar to the one triggered by 10 µM acetylcholine in brain miero vascular endothelial cells (BMVECs) and brain-derived Endothelial cells.3 (bEnd.3)^[1].
Muscarine (1-30 μM; 2 min) produces a dose-dependent hyperpolarization in a sub-population of the nucleus raphe magnus (NRM) cells that contain 5-hydroxytryptamine (5-HT) on the NRM neurons with an EC₅₀ value of 2.7 µM^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
