An improvement of the EpiTitan arrays over the previous histone peptide array platform includes the ability to perform multiple experiments per array using the multiwell gasket. The gasket facilitates the independent interrogation of each sub-array.
Test different proteins or antibodies
Examine multiple dilutions of the same antibody
Include a positive control with your experiment
The gaskets include a built-in cover with small ports for convenient addition and removal of reagents, visible on the image to the right (arrow).
