体外実験

L-778123 alone does not have obvious cytotoxicity on HT-29 and A549 cell lines (IC₅₀: >100 μM), but can generate synergistic effects with Doxorubicin (HY-15142A), with the decreased IC₅₀s of 1.72 and 1.52 μM respectively^[2].
L-778123 inhibits myeloid leukemia cell proliferation with IC₅₀ values of 0.2 μM-1.8 μM for cell lines, and 0.1 μM-161.8 μM in primary samples^[3].
L-778123 (0-1 μM, 12 h; or 5 μM, 6 h) inhibits H-RAS prenylation in HL-60 cells, and inhibits phosphorylated MEK-1/2 level (5 μM, 24 h)^[3].
L-778123 (0-100 μM, 72 h) inhibits lymphocyte activation (marker: CD71 or CD25) and function in human PBMCs^[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.

Protocol 1

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

Solubility: ≥ 2.22 mg/mL (5.47 mM); Clear solution

This protocol yields a clear solution of ≥ 2.22 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 (22.2 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2 mg/mL (4.93 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 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 3

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2 mg/mL (4.93 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 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.
