Key Capabilities
We are able to modify the polystyrene surface to meet your specific application.
Three different types of Thermo Scientific surfaces: • Passive Adsorption Surfaces • Covalent Surfaces• Affinity Capture Surfaces

Passive Adsorption Surfaces
Bio-molecules are bound to the surface via several non-covalent bonds.The collective force can be substantial.
• In general, larger molecules bind better• Most successfully used for proteins (Antibodies)• Moderate success with moderate complex to complex lipids

Passive Adsorption Surfaces
Guide to recommended biomolecule to be bound onto the passive adsorption surface.

Covalent Surfaces
Biomolecules are attached to the surface by strong covalent bonds.• Involves forming a bond between
a functional group such as NH2 on the biomolecule and another functional group incorporated into the surface of the plate
Advantages• Binding is not size dependent• Several biomolecules that do not
bind well on passive surfaces can be immobilized - peptides, nucleic acids, highly charged proteins
• Better molecular orientation produces higher signals and greater assay sensitivity

Covalent Surfaces
Spontaneously reactive electrophilic group
Peptide
Optimal distance ensures minimal steric hindrance

Covalent Surfaces
Immobilizer Amino• Covalent attachment of peptides,
proteins and antibodies(pH dependent)

Affinity Capture Surfaces
Plate surface is pre-coated with a specific capture molecule:
CAPTURE• Streptavidin• Nickel-Chelate• Glutathione
LIGAND• Biotin• Poly-histidine• Glutathione-S-Transferase
