In Vitro

Rehmannioside A (0-100 μM; 24 h) can improve high-glucose-induced decrease in cell viability and inhibit apoptosis and oxidative stress in HK2 cells (increasing the activities of SOD and CAT, reducing the levels of MDA, and decreasing LDH release and ROS production). The mechanism is involved in the inhibition of p38 MAPK and ERK1/2 phosphorylation^[1].
Rehmannioside A (0-80 μM; 48 h) inhibits the release of pro-inflammatory mediators and promotes M2 polarization in LPS (HY-D1056)-treated BV2 cells. The mechanism is related to the inhibition of NF-κB and MEK signaling pathways^[2].
Rehmannioside A (80 μM; 48 h) reduces neuronal apoptosis and restores the expression of anti-apoptotic protein Bcl-2 in the co-culture system of PC12 and BV2 cells^[2].

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: ≥ 1.25 mg/mL (2.38 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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: ≥ 1.25 mg/mL (2.38 mM); Clear solution

This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

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.
