The fin configuration provides shorter diffusion distance to the surface, reducing incubation times. Modules - Each plate consists of 1 x 8 breakable strips. These strips are assembled in a patented designed frame which locks each well into place by a spring lock. This spring lock design orientates each well at the same horizontal level allowing uniform washing and reading. CovaLink Modules - These plates can be used to bind proteins, peptides, DNA or carbohydrates.
Covalent linkage occurs via secondary amine group.
This allows a specific orientation and provides improved stability compared to passive adsorption due to chemical binding between molecules. Binding of molecules on PolySorp and MaxiSorp surfaces is obtained by passive adsorption. The covalent binding can immobilize small molecules such as biotin or peptides which may otherwise bind weakly by physical adsorption and facilitate the recognition by detection molecule. The transparent polystyrene plates give a low background fluorescence and are optimal where a read-through system is used. Black modules reduce background fluorescence and minimize back-scatter light which is often encountered in epifluorescence.
