3D surfaces for all SKi Sensor™ chips are prepared to have extremely low non-specific binding. Complex biological fluids like plasma can be used without deleterious effects.

Covalent chemistries currently available:

• Benzalydehyde Chip: Does not require an activation step. Protein is crosslinked offline with stoichiometric amount of linker, then conjugated to the surface.
• Carboxyl Chip: Amine-coupling.

Available soon:

• NTA-Ni Chip
• Protein A Chip

Non-covalent chemistries currently available:

• Streptavidin Chip: For small proteins and peptides.
