Poly-L-Arginine Coated Surfaces
biomat has developed a polystyrene surface with physically adsorbed poly-L-Arginine. The monomeric L-Arginine chain shows a high density of groups:
- α-amino
- α-carboxyl
- guanidino
these groups are able to react trough electrostatic and stereospecific bonds.
The polystyrene optical features don’t change, allowing the modified surface to be used as a valid tool to carry our biological tests.
This surface shows its usefulness for these applications:
- interactions with serino proteases
- interactions with maturation promoting factors
