Product Introduction

Bioactivity

Description	Rostafuroxin (PST 2238) has been used in trials studying the treatment of Essential Hypertension.
Targets&IC50	K+-ATPase:1.5 nM, Na+-ATPase:1.5 nM
Kinase Assay	Kinase assay: Activity assays are conducted using Lance Ultra time-resolved fluorescence resonance energy transfer (TR-FRET) technology from Perkin-Elmer. Briefly, 10 ng/mL FLT3 enzyme, a serial diluted G-749, 80 nM substrate of ULight-poly-GT peptide and variable amounts of ATP (8.5 μM to 1088 μM) are mixed in kinase assay buffer (50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM EGTA, 2 mM DTT and 0.01% Tween-20) and are added to a 384-well OptiPlate-384 in a volume of 10 μL. Kinase reactions are incubated at room temperature for up to 1 h and then stopped by the addition of 5 μL of 10 mM EDTA. A volume of 5 μL of the specific Eu-labeled-anti-phosphopeptide antibody diluted in LANCE Detection Buffer is then added to a final concentration of 2 nM. After 30-minute incubation, assay plates are incubated at 23°C and the LANCE signal is measured on an EnVision Multilabel Reader. Excitation wavelength is set at 320 nm and emission monitored at 615 nm (donor) and 665 nm (acceptor). The IC50 is calculated using nonlinear regression analysis analysis by GradPad Prism 5.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
