PeptiGel® Technology

 

Next-generation self-assembling peptide hydrogel (SAPHs) 

Short synthetic peptides self-assemble into stacks that develop into 3D nano-fibrous matrix hydrogel networks 

Meet the Family

 

The PeptiGel family. Finely tuned (for charge, elasticity) peptides which may be functionalized (PLUS versions) with bioactive peptide motifs

Tailored for each tissue and cell type

PeptiGel is a family of related hydrogel formulas that provide 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.

Of course, PeptiGels may be diluted to optimize viscosity. You can be assured that 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 each PeptiGel® can be tuned to create bespoke products to suit your cells’ needs. This includes functionalizing a PeptiGel® 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.  

KeyTechnology Benefits

PeptiGels® peptide hydrogels are fully synthetic and spontaneously self-assemble to form 3D nano-fibrous hydrogels that mimic the native extracellular matrix (ECM). The mechanical stiffness of these hydrogels is modulated and matches the stiffness of most tissue types. The fibre surfaces can be (bio)chemically functionalised with several biomimetic peptide sequences from key ECM proteins that are proven to signal and enhance biological processes. These include RGD (fibronectin), IKVAV (laminin), YIGSR (laminin) and GFOGER (collagen). The ability to tune the properties of the peptide hydrogels to provide the optimal environment for your cells’ needs, makes them the ideal synthetic alternative to animal-derived matrices such as Matrigel™, Geltrex™ and collagen. As peptides are the building blocks of nature, PeptiGels® are inherently biocompatible and provide a suitable environment for cells to survive and thrive

 

Webinar: How to Successfully Make the Switch to Synthetic Peptide Hydrogels 

 Professor Aline Miller (University of Manchester) and Sebastian Doherty-Boyd (University of Glasgow) discuss the difficulties in producing consistent cell culture results using traditional biomaterials, particularly animal-derived matrices with their inherent variability. They also discuss how to gain greater control over 2D and 3D cell culture with PeptiGels and cover specific examples of using PeptiGels to generate 3D tissue and disease models. Published: September 2023

 

Comparison of 2D cell culture and 3D cell culture with PeptiGel®

PeptiGels® can be used for 2D and 3D cell culture, and have been proven successful in supporting a range of application areas. See how they compare. 

 

2D vs. 3D cell culture

2D Cell Culture

3D Cell Culture

Not representative of the in-vivo environment Better simulation of the in-vivo environment
Altered cell-to-cell interactions and signalling Enhanced cell-to-cell interactions and signalling
Need for animal testing for validation Reduction in animal usage
Limited in its application areas Wide-ranging applications e.g. integration of fluid flow and bioprinting
Lack of in-vivo predictivity Reliable and relevant results
Simple to analyse Improved method to model diseases
