Polylysine surfaces contain positively-charged amine groups that enhance attachment of negatively-charged proteins and cells. Polylysine surfaces are popular for culturing cell lines derived from nerve tissue (e.g. neurons, glial cells, fibroblasts, epithelial cells).
The basement membrane extract (BME) contains multiple extracellular matrix proteins, including laminin and collagen. Surfaces coated with BME support cell culture assays of epithelial cells, endothelial cells, muscle cells and stem cells.
