CytoGrow™ Recombinant Fibronectin Fragment (Human), HEK293, His Tag

high-quality recombinant human fibronectin produced in HEK293 cells to ensure proper folding, relevant post-translational modifications, and strong biological activity. Featuring a His tag for efficient purification and consistent quality, this protein supports reliable performance across research applications.

Fibronectin is a key extracellular matrix (ECM) glycoprotein that plays a critical role in cell adhesion, migration, proliferation, and differentiation through interactions with integrins and other ECM components.

This recombinant fibronectin is widely used as a coating substrate for cell culture to promote cell attachment and spreading, as well as a functional component in 3D culture systems and tissue engineering models. It is also well-suited for studies in wound healing, angiogenesis, and tissue remodeling, providing a defined and reproducible alternative to traditional ECM sources.
