Isolation of protein from plant leaves.
It would really depend on the stability of the individual protein. Why don't you try running some fresh protein next to the week old stuff on an SDS-PAGE gel, and compare the bands to assess any degradation?
For a pure virus, HA can be considered as a way of representing their titre. even though it is cost effective and less labor intensive, it is less concerned. Kindly guide me in this matter.
