Western Blot Analysis^[2]

Cell Line:

N2asw
Concentration:

50 μM
Incubation Time:

18 h
Result:

Reduced Aβ levels, induced a significant increase in APP-CTFs, and significantly reduced the production of CTFγ.

In Vivo

Prazosin (1 mg/kg, injected into the abdomen once daily, two weeks) can prevent memory deficits in mice by altering the release of inflammatory mediators and astrocytes, alleviating symptoms of Alzheimer's disease^[2].
Prazosin (0.1-2 mg/kg, 3-6 mM, administered systemically or locally, in a single dose) can promote fear extinction in mice^[3].
Prazosin (0.01-1 mg/kg, subcutaneously, in a single dose) can enhance the analgesic effects of morphine in mice^[4].

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

Animal Model:

APP23 mice^[2]
Dosage:

1 mg/kg; daily; 2 weeks
Administration:

Intraperitoneal injection (i.p.)
Result:

Increased mean freezing time during acclimation, attenuated hippocampal-dependent memory decline, did not affect APP processing or Aβ aggregation in vivo, and increased the number of astrocytes and secretion of anti-inflammatory mediators in APP23 mice.

Animal Model:

C57B1/6N mouse^[3]
Dosage:

0.1-2 mg/kg; 3 and 6 mM; single dose
Administration:

systemic (0.1-2 mg/kg) or local microinjections (3 or 6 mM) into the prelimbic division of medial prefrontal cortex or basolateral amygdala
Result:

Had no effect on fear memory, but indirectly promoted fear extinction by interfering with the initial fear acquisition process.

Animal Model:

C57BL/6J mice^[4]
Dosage:

0.01, 0.1, 0.25, 0.5, 1 mg/kg; single dose
Administration:

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: ≥ 5 mg/mL (13.04 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.

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.
