Product Introduction

Bioactivity

Description	Fluorescein-PEG4-acid is a PEG-based linker for PROTACs, joining two essential ligands crucial for forming these molecules and enabling selective protein degradation via the ubiquitin-proteasome system within cells.
In vitro	PROTACs contain two ligands connected by a linker: one ligand targets an E3 ubiquitin ligase, and the other targets the desired protein. By leveraging the intracellular ubiquitin-proteasome system, PROTACs selectively degrade specific proteins [1].

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

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH₂O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH₂O TargetMol | reagent

mix well and clarify

For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.

All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
