Biomaterials for cell culture can foster the development of new cell-based therapies, support tissue engineering, aid the discovery of new drug targets and improve our understanding of cell behavior. Importantly, in vitro tests using human cells and tissue are proving to be an effective alternative to animal testing. 

Gelatin is a highly versatile and reliable biomaterial derived from native collagen, a natural protein found in the extracellular matrix of animals. Its unique properties, including cell recognition sites, excellent biocompatibility, low antigenicity and tunable biodegradability, allow researchers to create intricate three-dimensional microenvironments that encourage cell adhesion, growth, differentiation, migration, signaling and survival.

Rousselot – your expert partner for cell culture

We supply much more than gelatin:

  • Unparalleled expertise: our experienced team works closely with our customers to understand their unique requirements
  • Customized gelatin solutions: our wide range of high-quality products can be tailored to your specific cell type or application
  • Seamless support services: our formulation support, technical support and regulatory support teams can help you to get the most from our products
  • Supply chain security: from the global leader in gelatin solutions
  • We offer a wide choice of purified gelatins with very low levels of endotoxins and impurities. 
  • X-Pure® gelatins include hydrolyzed and non-hydrolyzed grades for 2D cell culture coating, as well as functionalized gelatins such as X-Pure®GelMA and X-Pure®GelDAT, each with distinct properties suited to 3D culture applications.
  • We understand the importance of adapting gelatin properties to different cell origins, e.g. liver cells need a softer environment than bone cells. All our X-Pure® gelatins can be customized to meet your specific needs.
  • Consistency of our products from batch to batch is essential in our production process, guaranteeing the uniformity and quality our customers expect.
  • Our research-grade X-Pure® gelatin is functionally equivalent to its GMP grade, minimizing the need to revalidate R&D results prior to clinical or non-clinical trials, and helping you speed your biomedical innovation to market.  
  • All Rousselot products comply with the regulatory requirements of the major pharmacopoeias, including raw material requirements of the EU Medical Device Regulation (MDR) 2017/745, (IVDR) 2017/746 and US-FDA guidance for (in vitro) medical devices, and come with traceability as required by ISO 22442.

In a number of studies, X-Pure® has outperformed standard research grade gelatins and coating materials, supporting successful cell culture.

With ultra-low impurity levels, X Pure® supports the reproduction of human body conditions and paves the way for successful cell growth, differentiation and communication.1

A recent study demonstrated that Rousselot’s purified GMP-grade gelatins support cell morphology and efficient stem cell proliferation, outperforming standard non-endotoxin purified research grade gelatins and other coating materials in 2D cell culture.2
