Descripciòn

M40 is an antagonist or a weak agonist for galanin receptor depending on different subtypes of galanin receptors in the brain, hypothalamus, hippocampus, amygdala and pancreas^[1]^[2]^[3].

In Vitro

M40 (1 μM) displaces [mono[¹²⁵IJodo-Tyr²⁶]galanin from binding sites in the hippocampus, hypothalamus, and spinal cord. M40 has a lower affinity than galanin for all membranes. The IC₅₀ values are 6 nM in the hippocampus, 15 nM in the hypothalamus, 12 nM in the spinal cord, and 3 nM in the insulinoma cells. M40 (1 μM) completely blocks ¹²⁵I-labeled galanin-binding sites^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .

In Vivo

M40 (0.1-1 nmol, intracisternal injection, single dose) blocks selectively the central cardiovascular responses induced by galanin-(1–15) in Sprague-Dawley rats models, according to the recognization of galanin receptor in N-terminus^[1].
M40 (2-8 nmol, intraventricular or intrahippocampal, single dose) exhibits antagonist efficacy against galanin on memory tasks in sprague-dawley rats models, exhibits potency in alleviating the cognitive deficits associated with Alzheimer's disease^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Vasopressor and tachycardia induced by galanin in Sprague-Dawley rats^[1]
Dosage:

0.1-1 nmol
Administration:

Intracisternal injection, single dose
Result:

Blocked the feeding effects of galanin in the hypothalamus and amygdala.
Reduced vasopressor response and heart rate induced by galanin-(1-15), but not those effects induced by galanin-(1-29).

Animal Model:

Memory impairment induced by galanin in rats model^[2]
Dosage:

2-8 nmol
Administration:

intraventricular or intrahippocampal, single dose
Result:

Blocked the impairment in choice accuracy.

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.
