Bespoke. Not one-size-fits-all. Reliable, simple, defined, and tunable. PeptiGels® is a family of related, but distinct synthetic self-assembling peptide hydrogels (SAPHs) that provide a canvas for 3D cell culture and bioprinting. PeptiGels® have been independently and extensively validated against numerous cell lines (over 40 and counting). PeptiGel® hydrogel's fully-defined components enable consistent product quality and reproducible results. This provides a tailored, better alternative to traditional animal-derived hydrogels. 

PeptiGel Self-Assembling Peptides Technology

We offer a range of class-leading SAPHs and bioinks to support your cell culture applications. The proprietary hydrogel technology allows us to tune mechanical and functional properties, to provide you with the most suitable materials tailored to your application's needs. PeptiGels® are physiological and biologically relevant hydrogels that mimic the cell micro-environment and provide a synthetic extracellular matrix.

Bespoke Peptide Hydrogel Design

The chemistry, mechanical and bio-functional properties of PeptiGels® can be tuned to create bespoke products to suit your cells’ needs. This includes functionalizing PeptiGels® with peptide sequences from collagen (GFOGER), fibronectin (RGD), & laminin (IKVAV or YIGSR). We can also tailor the material properties to precisely fit your requirements for a wide range of application areas, including cell therapies, drug delivery, and high-throughput screening.

If you require specific material design characteristics or assistance choosing the PeptiGel® that's most suitable for your application, please get in touch.
