In Vitro

TGF-β1/Smad3-IN-1 (100-500 nM; 48 h) leads to a decrease in TGF-β1 levels in H2228 cells, which is better inhibited than Nintedanib (HY-50904) at the same concentration^[1].
TGF-β1/Smad3-IN-1 (2-6 μM; 24 h) shows dose-dependent inhibition of p-Smad3 and α-SMA expression and significantly inhibits NIH3T3 cell migration^[1].
TGF-β1/Smad3-IN-1 (3-10 μM; 72 h) increases Cleave-casepase3 expression in NIH3T3 cells and dose-dependently induces apoptosis^[1].
TGF-β1/Smad3-IN-1 has an IC₅₀ of 1.07 μM for NIH3T3 cells. IC₅₀ for TGFβ1-activated HFL1 cells is 2.86 μM. TGF-β1/Smad3-IN-1 is found to be effective in inhibiting the expression of α-SMA^[1].

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: ≥ 5 mg/mL (8.64 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (8.64 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
