Alkyne-PEG4-maleimide
😃Good
Catalog No. T14183Cas No. 1609651-90-2
Alkyne-PEG4-maleimide is a PEG-based bifunctional linker designed for the construction of PROTAC molecules, enabling covalent conjugation between ligand moieties via its terminal alkyne and maleimide groups, and facilitating selective protein degradation through ubiquitin–proteasome system recruitment.

Chemical Properties
| Description | Alkyne-PEG4-maleimide is a PEG-based bifunctional linker designed for the construction of PROTAC molecules, enabling covalent conjugation between ligand moieties via its terminal alkyne and maleimide groups, and facilitating selective protein degradation through ubiquitin–proteasome system recruitment. |
| In vitro | PROTACs consist of two ligands connected by a linker: one binds to an E3 ubiquitin ligase, and the other targets a specific protein. They utilize the intracellular ubiquitin-proteasome system to selectively degrade their target proteins[1]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
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 . A total of 10 animals were administered, and the formula you used is 5% 
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 (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.
(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 main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
