Poly-D-Lysine serves as a positively charged extracellular matrix, fostering nonspecific cell attachment. Upon application to solid-phase culture surfaces, it heightens the electrostatic interaction between negatively charged ions on the cell membrane surface and positively charged ions on the culture surface. This enhancement bolsters cell attachment rates in serum-free or low-serum culture settings and reinforces the absorption of serum proteins and extracellular matrix proteins onto the culture surface.

GVS Poly-D-Lysine-coated Products are available in a variety of forms, including culture plates and dishes. The product surface is pre-coated with Poly-D-lysine, which facilitates the attachment growth, proliferation and differentiation of cells that are difficult to culture, such as neurons, glial cells and transfected cell lines.
