Customer Review

Based on 1 Customer Validation

22 (R)-Hydroxycholesterol (Narthesterol) is a natural oxysterol, acting as a LXRα agonist that inhibits cancer cell proliferation. 22 (R)-Hydroxycholesterol activates LXRα-mediated upregulation of downstream ABCA1 expression, enhances apolipoprotein-dependent cholesterol efflux, reduces intracellular cholesterol content, and decreases the production of β-amyloid peptide. 22 (R)-Hydroxycholesterol induces the differentiation of human mesenchymal stem cells into functional dopaminergic neurons. 22 (R)-Hydroxycholesterol is applicable to research related to cancer, Alzheimer's disease, and Parkinson's disease.

In Vitro

22 (R)-Hydroxycholesterol (22R) (10‑20 μM; 24 h) combined with 9‑cis‑Retinoic acid (HY-15128) upregulates ABCA1 expression, enhances cholesterol efflux, modulates APP processing, and diminishes Aβ secretion in H4APPsw and CHOAPPsw cells^[1].
22 (R)-Hydroxycholesterol (22-HC) (2 μM; 14 days) induces the differentiation of human BM-MSCs, AD-MSCs and DP-MSCs into dopaminergic neurons. Among them, DP-MSCs show the highest differentiation efficiency (80.20% of MAP2-positive cells), with the most significant upregulation of dopaminergic markers and functional properties^[2].
22 (R)-Hydroxycholesterol (30 nM-3 μM) activates LXRα in transfected HEK293 cells. Significant activation is observed at a concentration of 1 μM, and an even higher level of activation is detected at 3 μM^[3].
22 (R)-Hydroxycholesterol (1-12 μM; 96 h) inhibits the proliferation of the human prostate cancer cell subline LNCaP in a dose-dependent manner, with an EC₅₀ value ranging from 4.7 μM to 6.3 μM; it also inhibits the proliferation of various human cancer cell lines in a dose-dependent manner, with EC₅₀ values ranging from 7.0 μM to 10.1 μM^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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% EtOH 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (6.21 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 EtOH stock solution (25.0 mg/mL) to 900 μL Corn oil, 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.
