Can I use Zeba Desalting plates with a vacuum manifold, and if so, are there any specific considerations or limitations to keep in mind?
Yes, Zeba Desalting plates can be used with a vacuum manifold. Unfortunately, we do not offer a protocol for the same. It is important to note that the pressure settings of the vacuum manifold will need to be optimized for each instrument as the pressure apparatus may differ. Additionally, it has been reported that protein recovery with Zeba Desalting plates using a vacuum manifold may be lower compared to the traditional centrifugation workflow.
