Poly-Lysine enhances electrostatic interaction between negatively-charged ions of the cell membrane and positively-charged surface ions of attachment factors on the culture surface. When adsorbed to the culture surface, it increases the number of positively-charged sites available for cell binding.
Collagen is the most abundant mammalian protein and the main component of connective tissues. Typically collagen is first synthesized as individual glycine-rich preprocollagen monomeric strands from the ribosomes in the rough endoplasmic reticulum (RER).
