PODS® Human DKK-1 in combination with your choice of PeptiGels. PODS-PeptiGels combines two existing cell culture technologies - sustained release growth factors (PODS®) and synthetic peptide hydrogels (PeptiGels®). Together, these provide a reproducible and highly controlled environment for 3D cell culture. The ready-to-use PODS-PeptiGel kits allow researchers to tailor their cell culture system to suit their individual cell types by selecting specific growth factors and peptide hydrogel combinations for a truly relevant in vitro system.
