In Vitro

DAMGO (1-10 μM) significantly reduces the activation of neuronal Akt and ERK1/2 by CXCL12 and inhibits CXCL12-promoted neuronal survival, but does not down-regulate CXCR4 protein expression^[2].
DAMGO (1 μM) effectively inhibits the prostaglandin E 2 (PGE 2) induced increase in a tetrodotoxin-resistant voltage-gated Na⁺ current (TTX-R I _Na), i.e. PGE 2 (1 μM) can increase the TTX-R I _Na peak by 103 % compared to 24.9 % with the addition of DAMGO^[3].

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

In Vivo

DAMGO (i.v., 0.5-2 mg/kg) can produce significant anti-injury effects on injured paws of male Sprague-Dawley rats weighing 200-225 g in a dose-dependent manner, producing an effective and long-lasting analgesic effect^[4].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (4.87 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (4.87 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (4.87 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol

Cell Assay^[2]

Neurons (9 days in vitro) are treated with DAMGO (10 μM) for 24 h in their original culture dish, subsequently transferred to a dish containing Mg²⁺-free saline with glycine (15 μM), and exposed to NMDA (100 μM) and/or CXCL12 (20 nM) in absence of glia. After treatments, neurons are moved back into the original culture dishes containing glia. Neuronal death is evaluated after 24 h. Hoechst 33342 (3 μg/mL) combined with cleaved caspase-3 (1:100) staining is used to identify normal and apoptotic cells^[2].

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

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.
