Smart MCs Poly(ethylene glycol) diacrylate (PEGDA)

Smart MCs Poly(ethylene glycol) diacrylate (PEGDA) is a versatile, chemically defined hydrogel precursor essential for advancing cultivated meat research. It addresses the critical need for a highly controllable, animal-origin-free (ACF) scaffold that mimics the native cellular environment. This material provides a robust platform to precisely modulate mechanical and biochemical cues, which is fundamental for optimising cell proliferation and differentiation in 3D culture systems.

Composed of polyethylene glycol functionalised with acrylate groups, this specialised matrix acts as a biologically inert "blank slate." Its primary differentiator is the ability to achieve tuneable stiffness, size, and surface charge, allowing for the creation of a wide spectrum of mechanical properties. This flexibility ensures compatibility with diverse research requirements, distinguishing it from less adaptable scaffold materials.

Validated for use in 3D cell culture, tissue engineering, and biological 3D printing, PEGDA supports a range of mammalian cell types. Its rapid polymerisation capabilities, minimal energy requirements, and substantial water retention make it an optimised choice for creating high-fidelity scaffolds. The material is highly customisable, enabling the incorporation of biological molecules, such as RGD cell-adhesion peptides, to support species-specific attachment protocols.

Supplied as a kit including LAP photoinitiator in light-protective bottles. The standard polymer-to-LAP ratio is 10 g PEGDA per bottle with 0.5 g LAP. As a light-sensitive precursor, it must be stored in a dark place; it remains stable at room temperature for 3 months, at 4 °C for 12 months, or at -20 °C for up to 18 months. Long-term storage at -20 °C is recommended to ensure maximum shelf life for R&D and pilot-scale studies.
