Customer Review

Based on 1 Customer Validation

Roemerine is an alkaloid that has been identified from the leaves of Fibraurea recisa Pierre. Roemerine exhibits antibacterial, anticancer, and antidepressant activities, can reverse the multidrug resistance phenotype in cultured cells, and exerts antibacterial effects by regulating the cAMP signaling pathway. Additionally, Roemerine influences neuronal activity by increasing BDNF protein expression and modulating the serotonergic and glutamatergic systems. Roemerine holds promise for research in the fields of cancer, infections, and neurological diseases.

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

Protocol 3

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

Solubility: ≥ 2.5 mg/mL (8.95 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.

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.
