Immuno Breakable Modules Clear

We have tested and found that a 3 amino acid peptide (Pro, Leu, Gly) cannot be detected when passively adsorbed on the MaxiSorp surface. However, this peptide can be detected when covalently immobilized using CovaLink NH Modules and CovaLink NH2 Modules and Plates. Using covalent immobilization of small peptide residues, you can typically obtain a better orientation of the molecule and reduced problems with antibody recognition of the peptide due to masking of the epitope. We have discovered that a 7 amino acid peptide from the MHC Class II antigen can be detected when adsorbed on the MaxiSorp surface. We state that the detection limitation using the MaxiSorp surface is between 3 and 7 amino acid residues.
One additional note is that detection is contingent upon the orientation of the peptide when immobilized. If the active site is inactivated or hidden at the site facing the solid phase, no detection signal is observed.

Single-stranded DNA can be adsorbed to our MaxiSorp surface using approximately 10 µg ssDNA per mL PBS, pH 8.2, although the stability is uncertain. Based on our experience, ssDNA immobilized on the MaxiSorp surface is so loosely bound that it can be removed by stringent washing.
Double-stranded DNA will not bind to the MaxiSorp surface. DNA, however, can be covalently bound to Nunc NucleoLink Strips.

Our Thermo Scientific 8-Well Strip Caps for Immuno Standard Modules were designed to provide a positive seal for flat and round bottom wells of our Nunc MicroWell 96-Well Microplates and Nunc Immuno 96-Well Plates.
8-Well Strip Caps for Immuno Standard Modules are not compatible with C or V bottom wells of the Nunc Microwell 96-Well Microplates and Nunc Immuno 96-Well Plates.

Due to the locking feature design of the LockWell modules, the 8-Well Strip Caps for Immuno Standard Modules are not compatible with, and will not seal, the LockWell Modules.

The following list describes the geometries of wells available for Nunc Immuno-plates and modules:
- Flat bottom (F): Allows maximum transmission of light. These plates can be read on a monochromatic reader.
- Round bottom (U): This geometry optimizes washing and coating. These plates can be read using a dual wavelength reader.
- "C" bottom (C): This design of the well is a combination of both flat and round bottoms. Basically, it is a flat bottomed well with curved edges at the bottom. These plates also can be read using a monochromatic reader combining optimal reading and washing.
- StarWell: These wells have a modified "C" shape geometry with eight fins strategically placed at the bottom. This feature increases surface area, allowing more molecules to become immobilized which reduces incubation times.
