说明

General description

Tissue Engineering (TE) Grade Poly(ethylene glycol) methyl ether acrylate (PEGMEA) is an inhibitor‑free, monofunctional acrylate macromer engineered for clean, rapid polymerization and biocompatible hydrogel environments. Developed for tissue engineering workflows,TE PEGMEA is R&D‑tested for low cytotoxicity leading to high cell viability. It features a ≥90% degree of functionalization (acrylate end‑group) to support reliable crosslinking and high conversion. The PEG backbone provides excellent aqueous solubility and biocompatibility, supporting scaffold fabrication, bioinks, encapsulation matrices, and protein‑resistant surface coatings.
Key Features

Inhibitor‑free formulation (no added MEHQ/BHT) for efficient curing and minimal residuals.
R&D‑tested biocompatibility demonstrating low cytotoxicity and high cell viability in standard lab assays. ≥90% degree of functionalization for consistent free‑radical polymerization and robust network formation.
PEG biocompatibility and hydrophilicity to help reduce protein adsorption and support gentle cell handling.
High purity and quality control suitable for demanding tissue engineering research and prototyping

Application

Photocurable PEG hydrogels for scaffold fabrication and cell encapsulation
Bioinks for 3D bioprinting (with suitable crosslinkers/initiators)
Protein‑resistant surface coatings and soft network modifiers
Drug‑delivery matrix components and permeability tuning
