Acesulfame potassium

Customer Review

Based on 1 Customer Validation

Acesulfame potassium is a synthetic sweetener. Long-term use of Acesulfame potassium can affect cognitive function, possibly by altering the neurometabolic functions in mice. Acesulfame potassium can suppress autophagic degradation of PD-L1 in RIL-175 and SK-Hep1 cells through the ERK1/2-mTORC1-ULK1 pathway, which may be related to immune evasion in cancer cells. Acesulfame potassium can be used in research on neurological diseases, metabolic disorders, cancer, and immune evasion.

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 (12.42 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 (12.42 mM); Clear solution

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 (12.42 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.

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.
