X-Pure GelMA
What is X-Pure GelMA?
X-Pure® GelMA is the world’s first gelatin methacryloyl (GelMA or GelMOD) produced under GMP conditions1, making it suitable for clinical applications in advanced biomedical applications.
This premium biomaterial is ideal for 3D bioprinting, regenerative medicine and tissue engineering owing to its guaranteed ultra-low impurity levels, batch to batch consistency and tunable mechanical properties. As a result, X-Pure GelMA can reduce the development time between bench and bedside, for pharmaceuticals, medical devices and Advanced Therapy Medicinal Products (ATMP).

How X-Pure GelMA works
A GelMA hydrogel allows the formation of 3D architectures that are stable at body temperature. X-Pure GelMA rheological properties can be customized by varying the degree of modification (the number of crosslinks between gelatin protein chains) and the gelatin molecular weight, making it one of the most versatile hydrogels available for 3D cell culture and drug delivery systems2.
Figure 1. The methacrylamide side groups are photo crosslinked in the presence of a photo initiator and UV or visible light, creating a viscoelastic gelatin network. The degree of modification (number of methacrylamide side groups) and molecular weight can be tuned for different biomedical applications.

Advantages of X-Pure GelMA
Rousselot’s X-Pure GelMA stands out by offering several unique advantages.
High batch-to-batch consistency
The X-Pure GelMA standardized production process allows for high reproducibility and controllability in terms of composition and biophysiochemical properties. Lower material variability means a higher signal-to-noise ratio for your trials.
Figure 2: Producing GelMA at the lab scale based on processes described in the literature often results in products with a high variability in methacryloyl functionalization and molecular weight, causing variable mechanical properties. This can mainly be attributed to the lack of process controls at lab scale. The same variability however is also seen in many commercial GelMA products, which use a similar process.

Ultra-purified, suitable for sensitive applications
Rousselot’s process securely removes precursor and process impurities, resulting in consistent and ultra-low impurity levels, making X-pure GelMA gelatins suitable for sensitive applications.
Figure 3: Analysis of commercially available GelMA products shows a high and variable level of soluble impurities such as LPS, Methacrylic acid (MA) and DNA, and even insoluble debris in all products (pellets after centrifugation of 1-ml of 8% w:w solutions).

GMP grade & scalable production process
X-Pure GelMA is the first commercially available GMP GelMA. X-Pure Research grade and X-Pure GMP grade are functional equivalence products, meaning requalification efforts when switching to the GMP product can be avoided. This can accelerate translation from lab to clinic.

Tunability:
GelMA hydrogels can be synthesized with a specific degree of functionalization (DoM) and molecular weight (MW) or adjusted to the intended application.
