PGmatrix™ Injection Platform

The best option for in vivo delivery of cells, virus, antigens, exosomes, other biologics, as well as targeted proteins and peptides. It serves as an “adjuvant” for biological drugs to improve drug efficacy.

PepGel™ PGmatrix™ Injection is an advanced, peptide-based hydrogel platform designed for minimally invasive in vivo delivery of therapeutic cells, biologics, and growth factors. By mimicking the native extracellular matrix (ECM), it provides a supportive and biocompatible environment that enhances cell retention, viability, and functional integration after delivery.

Fully synthetic and animal-free, PGmatrix™ Injection ensures high reproducibility and safety for preclinical applications. Its controlled degradation into natural amino acids enables gradual release of encapsulated cells or molecules, making it a powerful tool for cell therapy, drug delivery, and regenerative medicine research.
