Customer Review

Based on 1 Customer Validation

Glaucine (O,O-Dimethylisoboldine) is an alkaloid extracted from Glaucium flavum that possesses various activities, including cough relief, bronchodilation, anti-inflammatory effects, analgesia, antipyretic properties, and anticancer effects. Glaucine acts as a selective and orally active inhibitor of phosphodiesterase 4 (PDE4), with a K_i of 3.4 µM in human bronchial tissues and polymorphonuclear leukocytes. Glaucine induces relaxation of human isolated bronchi by antagonizing calcium channels. Additionally, Glaucine inhibits the activation of NF-κB, leading to a reduction in the expression of the MMP-9 gene, thereby suppressing the migration and invasion of breast cancer cells. Therefore, Glaucine holds potential for research in asthma and breast cancer.

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

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.
