Product description

Cytocaf® proteins are based on the bacterial protein Caf1, which associates into long, flexible and bioinert polymers. Bioactivity can be imparted by genetically encoding bioactive motifs into the protein’s sequence. Cytocaf® polymers are highly stable, modular and flexible.

Fibronectin Cytocaf® mimics the action of the extracellular matrix protein Fibronectin through a genetically encoded bioactive peptide that can bind to integrin receptors. This makes it adhesive for a range of cell types. These include, but are not limited to, human dermal fibroblasts, mesenchymal stromal cells (MSCs), epithelial-like cells (U2OS), hepatic cells (HEPG2), glioblastoma-derived cells (U118) and keratinocyte cells (CCD1106).

Cells grown on Fibronectin Cytocaf® display adherence and morphologies similar to those seen on recombinant Fibronectin, Geltrex™ and Matrigel™

Figure 2: (A) Non-TC coated plastic was coated with 2µg/cm² Fibronectin-Cytocaf batch 29. Human mesenchymal stromal cells were seeded in serum free media and grown for 72 hours. Images were taken by bright field microscopy at 10X magnification. (B) Human mesenchymal stromal cells were seeded in serum free media on uncoated, unmodified Cytocaf coated or Fibronectin-Cytocaf batch 29 coated non-TC plastic. The cells were grown for 24 hours prior to performing a Presto Blue cell viability assay, as per manufacturer’s specifications.
