Dear all, sorry, for the slightly off-topic theme, but I wonder if anyone has compared the above mentioned ultracentrifugation devices, thoroughly.
Currently, we are using the Amicon Ultra, but as the Vivaspins are considerably cheaper we are considering to change. I used both with extracellular matrix proteins and both worked fine for me; however, some of us are working with membrane proteins, which might behave differently. Has anyone experiences with Vivaspins and membrane proteins? Has anyone compared the two (also with non-membrane proteins) and can share her or his experience?
