In Vitro

Pterostilbene (0, 5, 25, 50, 100, 200 and 400 μM) shows inhibitory activity against the growth of HeLa cells, with IC₅₀s of 101.2 μM and 65.9 μM at 24 and 48 hrs, respectively. Ipterostilbene (0, 25, 100 and 200 μM) also induces the apoptosis HeLa cells^[2].
Pterostilbene (0.05, 0.1, 0.15 and 0.2 mM) has high anti-oxidant activity against DPPH, ABTS, hydroxyl, superoxide, hydrogen peroxide in a dose-dependent manner. Pterostilbene decreases lipid peroxides and hydroperoxides, reduces protein carbonyl groups and restores protein sulphydryl groups in response to damage by TBHP and As-Fe²⁺. Pterostilbene also inhibits single strand breaks in pBR322^[4].

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.

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

Solubility: ≥ 2.75 mg/mL (10.73 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 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 (27.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

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: 15% Cremophor EL 85% Saline

Solubility: 3.33 mg/mL (12.99 mM); Clear solution; Need ultrasonic

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.
