In Vitro

7α-Hydroxycholesterol (2.5-160 μM; 24 h) has cytotoxicity against 158N and C6 cells, with IC₅₀ values of approximately 15 μM and 40 μM, respectively^[1].
7α-Hydroxycholesterol (8 μg/mL; 2-4 h) significantly reduces the sterol synthesis rate and HMG-CoA reductase activity in primary hepatocytes or L-cell cultures^[2].
7α-Hydroxycholesterol (5 µg/mL; 48 h) increases the transcriptional level of TLR6, promotes the expression of CD14, and induces monocytes to produce chemokines such as CCL2, CCL3, and CCL4 in monocytes/macrophages. The mechanism involves the phosphorylation of Akt, Src, ERK1/2, and the p65 subunit^[3].

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: 10 mg/mL (24.84 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 10 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (100.0 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: 10 mg/mL (24.84 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 10 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (100.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

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

Solubility: ≥ 5 mg/mL (12.42 mM); Clear solution

This protocol yields a clear solution of ≥ 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 DMSO stock solution (50.0 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.
