Hi Manjula, I imagine that they could be reusable, if you stored them in a buffer with some sort of preservative like sodium azide (NB Toxic) or maybe a bacteriostatic agent like EDTA or something.
However, when you use them, a small amount of protein is going to remain in the cassette after each use, so I would only use each cassette for a specific protein to prevent cross-contamination. Additionally, I'd worry about protein from old preps falling apart/denaturing and then contaminating future fresh preps of protein. I guess it depends at what step during purification you are using them.
