Poly-L-Arginine Coated Surface shows a high density of groups α-amino, α-carboxyl and guanidino that are able to react through electrostatic and stereospecific bonds.

Poly-L-Arginine Coated Surface is a 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 through 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.

Examples of applications for Poly-L-Arginine Coated surface

  • interactions with serino proteases
  • interactions with maturation promoting factors
