Product Introduction

Shield-1 AI Summary

Shield-1 displays a strong binding affinity to various FKBP12 mutants. It binds to the human FKBP F36V mutant with a Kd of 2.4 nM and the human FKBP F36V/L106P mutant-YFP fusion protein in NIH3T3 cells after 24 hours, with an EC50 of 100.0 nM. It stabilizes the FKBP12 V2A mutant-YFP fusion protein with an EC50 of 60.0 nM and displaces fluorescein-SLF from the FKBP12 F36V mutant with a Kd of 0.4 nM. Additionally, it displaces fluorescein-SLF from FKBP12 mutants F36V, V2A, L50A, L106A with Kd values ranging from 2.0 to 4.0 nM. Moreover, microarray analysis in mouse NIH3T3 cells indicates that Shield-1 induces gene expression changes, positively affecting mRNA levels of Epb4.1l2, Csnkle, and Tcfe3 (FC 1.9 to 2.7) and negatively affecting MtCrVgp3, 4930422M22Rik, A430110N23, Ptpn1, Npas4, and Shkbp1 (FC -1.7 to -11.3). These findings suggest that Shield-1 has significant bioactivity and can modulate various cellular processes and pathways..

Bioactivity

Description	Shield-1 is a specific, high-affinity, and cell-permeable ligand for FK506-binding protein 12 (FKBP) and reverses instability by binding to mutant FKBP (mtFKBP), allowing conditional expression of mtFKBP fusion proteins.
Targets & IC50	FKBP12 V2A mutant-YFP fusion protein (NIH3T3 cells):60 nM, FKBP12 V2A mutant-YFP fusion protein (NIH3T3 cells):100 nM (EC50)
In vitro	METHODS: Transfected cells with mtFKBP-TRPV5 were treated with Shield-1 (1 μM, 24 hours), the ligand was washed out, and the mtFKBP-TRPV5 signal was subsequently measured at different time points. RESULTS mtFKBP-TRPV5 protein levels decreased rapidly with a half-life (t) of 2.53 ± 0.59 hours. [1]

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, and a total of 10 animals are to be administered, using a formulation of 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 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 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 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.
