Bikinin reduces transcript levels of NbRBOHB and BR-induced NbRBOHB expression in TRV:00, TRV:NbDWARF, TRV:NbBRI1, TRV:NbBSK1, TRV:NbBAK1, TRV:NbBIK1 and TRV:NbBSU1 plants. Bikinin largely inhibits BR-increased ROS accumulation. Moreover, Bikinin decreases the transcripts of these six genes in all plants, but fails to down-regulate transcripts of these genes in NbBES1/BZR1-silenced plants. Bikinin also inhibits BR-induced up-regulation of the six genes, and the inhibition effects are compromised in NbBES1/BZR1-silenced plants[1]. Bikinin is a potent inhibitor of group I and group II ASKs[2]. Bikinin directly binds the GSK3 BIN2 and acts as an ATP competitor. Furthermore, bikinin inhibits the activity of six other Arabidopsis GSK3s[3].

Solvant et solubilité
DMSO : ≥ 100 mg/mL (366.19 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- 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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocole
ASKs are expressed as GST-fusion proteins in Escherichia coli BL21. In vitro kinase assays are performed by incubating 50 ng GST-fusion protein, 10 μg myelin basic protein (MBP) as a substrate and 0.15 MBq γ-[32P]-ATP as co-substrate at 25°C for 30 min. The reaction buffer consists of 20 mM HEPES/KOH pH 7.4, 15 mM MgCl2, 5 mM EGTA, 1 mM dithiothreitol and 1 μM cold ATP. The reaction products are separated by SDS-PAGE and the amount of radioactivity incorporated into MBP quantified using an Amersham storage phosphor imager screen and a Biorad Molecular Imager FX[2].
