NOVATACH™ peptide-coupled alginates are designed to facilitate and promote interactions between cells and alginate-based scaffolds or matrices. NOVATACH™ peptide-coupled alginates are obtained from PRONOVA® UltraPure Alginates that have been modified to covalently graft peptide sequences. NOVATACH™ MVG GRGDSP is grafted with RGD peptide sequence, it is medium viscosity, low molecular weight and high-G content, leading to stronger gel formation.
