Biomat has developed a polystyrene surface with physically adsorbed poly-L-Arginine.
The monomeric L-Arginine chain shows a high density of groups:
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.
This surface shows its usefulness for these applications:
- interactions with serino proteases
- interactions with maturation promoting factors
Biomat ‘s Poly-L-Arginine surfaces are available on the following Biomat’s products:
Poly-L-Arginine is coated using 200 µl/well. The strips are post-coated (blocked) for low non specific binding and long-term stability.
Microplates show a CV% less than 5 when are used as a catcher of NHS-biotin in an ELISA format, using Streptavidin-HRP as detector and TMB as substrate
Storage and Stability
The microplates, if unopened, are stable refrigerated until the expiration date printed on the label. If opened, store in closed pouch with desiccant and use within the expiration date.
